delayNanoseconds

that didn't work either - ok going to do it another way

 

[Dogbone06]

@Paul, I know I'm not alone when I say that I'm curious to why you want to find the highest speed?
Makes one wonder what cool stuff you got going on behind the scenes * Coff * - 1170 - * Coff *. Cmon spill some beans for us!

If the SDRAM is made for 166MHz, going faster surely will shorten the lifespan and thus not be feisable on end user products. Or am I wrong?

 

[mjs513]

@mjs513 seems you are working on SDRAM_malloc? Might be handy to get valid controlled pointers with the 1062 doing the math. Will be using 5 or maybe 9 blocks for this - though they'll be single alloc. For fun I could switch up the alloc() ordering.

@defragster
Would rather wait and test the mods i mad to the core before I put it out there for testing - would be easier for me to debug than going back and forth. Still havent heard directly from fedex when it will be delivered but still assuming tomorrow. All I know is right now it left Charles de Gaule ap but thats about it.

If you want to try something look at the post #120 that was the initial way I had done it but what I am playing with now is working on putting it in the core in a kludgey way

 

[PaulStoffregen]

I'm curious to why you want to find the highest speed?

I'm curious about the DQS signal to maybe gain some insight (or just guesswork-based theories) about how NXP designed the chip. You asked, so I'm saying as clearly as possible, learning more about the plausible design of the IMXRT SEMC is my main interest here. That's why I'm curious.

Not curious enough to have you send me the hardware for free and do the testing myself, but curious enough to write several messages on this thread with info to help Defragster try it...

Important projects should of course stick to the official specs and avoid overclocking. But still, if we can learn more about the best capacitor to use, even standard 166 MHz might enjoy better timing margin. Maybe that's overkill and maybe not worth the cost of 1 capacitor. The more we know, the easier making that sort of judgement call could be.

Today we know a few things:

1: 166 MHz works without any capacitor
2: NXP says on their forum not to use any capacitor
3: DQS is used to adjust read timing
4: Someone designed the eval board with a place to add that capacitor...

Personally, for me, that leaves something to be desire knowledge-wise. I'm sure most people are happy that it works at 166 MHz and they don't need a capacitor, but it just leaves me wanting to learn more about it.

 

[KurtE]

Question: (@KurtE / @PaulStoffregen): why do those hardwareserial.h addMemory()'s take size_t params when head & tail are only 16 bits?
And availableForWrite() returns signed int?
virtual int availableForWrite(void); void addMemoryForRead(void *buffer, size_t length); void addMemoryForWrite(void *buffer, size_t length); ... size_t tx_buffer_size_; size_t rx_buffer_size_; size_t tx_buffer_total_size_; size_t rx_buffer_total_size_; ... volatile uint16_t tx_buffer_head_ = 0; volatile uint16_t tx_buffer_tail_ = 0; volatile uint16_t rx_buffer_head_ = 0; volatile uint16_t rx_buffer_tail_ = 0;

Sorry, it has been awhile...

You could probably change one or the others. Maybe should change the size_t to uint16_t as I doubt anyone with a Teensy would need more than 64K for a TX or RX buffer. Unless of course we are actually talking about a real PJRC product line, in which case maybe.

 

[Dogbone06]

@Paul

Thanks for explaining, it's always interesting to know what "turns people on". Yours seem to be knowledge among other things.

As promissed I will test it once I have a board.

 

[defragster]

TRY221 with no cap failed as before with NO_CAP -

Maybe start with 4.7pF, 10pF, 15pF, and of course no capacitor. That's 4 cases to test, which becomes 12 test to run if you try each at 166, 198, 221 MHz.

Hopefully just those 12 results will show whether any further testing makes sense, and give some insight on where to focus more tests.

The sketch works to show, then stops. Will see about CAPS

The sketch works to show, then stops

I don't understand "works to show". What does that mean?

But as I tried to explain in msg #62, the test should be modified so it counts the number of reads which gave wrong data rather than simply stopping at anything wrong. It should continue for the entire memory. Then it should report the total number of incorrect reads, not simple pass/fail. The final result after running all patterns should be the total number of incorrect reads across all the tests.

Ideally, each pattern should write once to fill the entire memory, than read the whole memory 100 or 1000 times. We're expecting timing problems to manifest with reading. The test should always continue for the entire memory size. The reported result should be the total number of incorrect reads.

The idea is to push the clock frequency to the point where we have very little timing margin and test how frequency read errors start to occur. So that would always fail on a simple pass/fail test, but we want to see and compare how much it's failing to read when given little timing margin. Then by tweaking C29, we'll (probably) see differences in the amount of failing reads.

 

[defragster]

that didn't work either - ok going to do it another way

on second reading - The error said 'not found' - next post shows it needed the #include according to PJRC sources

 

[mjs513]

Tim - just noticed in your post #146 to add core_pins.h. That got it working for micros() and delayMicros() - my eyes must have been too tired last night to read messages straight.

 

[mjs513]

@defragster

Ok now I will let you do a quick try. Add/replace the files in the zip to the teensy 4 core.

There is one file called hasSDRAMKludge.h which has a single define in it. Will allow enabling SDRAM usage and disabling it by just commenting out the define. Its just a kluge for testing - not 100% happy doing it that way but was the simplest.

Now you shouldn't need the library and use EXTSDMEM to specify using sdram memory (only temporary until I am sure everything is working will then just make it EXTMEM

To use - use just like EXTMEM:

EXTSDMEM uint8_t test[4096];

'Stops" with fast blink as your original sketch did once an error is detected.
will edit with this in mind:

The capacitor is expected to matter only for reading. So perhaps a test program might look similar to the PSRAM memory test, but for each pattern it would probably write the entire memory once and then read it all back thousands of times, since we're expecting the problem to manifest as occasional bad reads. It would probably count the total number of incorrect words read to report at the end of all patterns, continuing the test for all patters rather than stopping when any fails. You'd want a total count of errors rather than simple pass/fail, so you could compare results and say one "failed" test gave fewer errors than another.

Test runs going to get VERY long when it gets to thousands ... 'only a small number of tests'

So SDRAM and PSRAM will both have the same macro? How does the code know which is which?

Right now they are different.

But remember PSRAM isn't supported on the Teensy Micromod!. As Paul mentioned in a very early post why would you use PSRAM when you have SDRAM. But I have no issue keeping then separate. Remember these changes aren't permanent - anybody developing there own boards in the future would have to modify the ld file. I modified the TMM one just for our testing - don't think it would do much of anything if a SDRAM wasn't present anyway

Look in the pgmspace.h file - you will see the macros for extmem and extsdmem

Technically you can use PSRAM on a Micromod based custom board.
I put together a small library that allows me to use PSRAM on an older devboard that @Dogbone06 sent me a few month back, which has the 16mb flash chip just like the Micromod - Just copied some of the code from the cores and used a custom linker defined in my build settings.
I implemented it with PlatformIO, without the need to change cores at all.

Therefore I think it would be best to have a separate macro for SDRAM as you have already implemented

Reading ... over rated {see p#162 re: p#62 }
I should have found p#146 that on first search - would have been less confusing for BOTH of us.

Looks like new UART test on hold until the change to 'accept and count errors works'. Easy to find ERR's at 212 MHz one pass - just need to make continuing and stopping and logging work. Then I'll look to integrate the EXTSDMEM changes. So that is just compile reserve - not the smalloc() tie in for SDRAM?

<edit> Then we just need a working LittleFS_SDRAM - will be faster than PSRAM! Probably the same with EXTSDMEM myMem[]. Then the INTEGRITY test for that could run.

I have a product based on the Micromod, but it’s a custom board just like the dev board. On it I have the 16MB flash and 16MB PSRAM, so it’s detected as a Micromod but I use EXTMEM with a modified .ld file.

 

[defragster]

@PaulStoffregen, here is the start of continuing after errors for a finite #define ERR_ABORT number seen.
It continues testing on the next test. This is at 212 MHz so fails are immediate. If some passes with 1 read, then 6 reads pass while in loop() it adds 60 more passes and repeats (until 2,500) reads. Any failure at that point would look something like this, where "Read Cnt 0" indicates it failed on the first pass:

Technically you can use PSRAM on a Micromod based custom board.
I put together a small library that allows me to use PSRAM on an older devboard that @Dogbone06 sent me a few month back, which has the 16mb flash chip just like the Micromod - Just copied some of the code from the cores and used a custom linker defined in my build settings.
I implemented it with PlatformIO, without the need to change cores at all.

Therefore I think it would be best to have a separate macro for SDRAM as you have already implemented

Very cool - right now they are separate - so we can leave them it that way - not a big deal.

Below is one loop() iteration of a 1.5 hour run with re-reads incrementing from [1 to 51] 5 more reads each pass on the 13th pass. It took 13 minutes for 57 tests with the 51 write and re-reads on each test (re-read dots scaled to stay on screen). Overall that is 2,907 re-reads - but on 741 sets of values (fixed and random). At 198 MHz single write and last successful read taking 20.27 seconds.

For the UART test there will be some of the EXTSDMEM[] blocks that will be written once and re-read and validated for the test duration as it cycles. They'll be at least 4 blocks of some 60KB where two are read and compared against each other, some 'x' times per minute.

[PaulStoffregen]

@PaulStoffregen, here is the start of continuing after errors for a finite #define ERR_ABORT number seen.

I'm glad you're doing this testing, but for the sake of comparing C29 capacitors this type of output is both too much spew and lacking the essential result.

First, to be able to compare results against each other, it's critically important that the test always perform the same amount of work. Whatever number of times each pattern is read back needs to be consistent, no matter how many fails. The purpose is to attempt a fixed number of reads and count the number of those reads which fail.

Only 1 number matters at the end, the number of reads which gave wrong data. I see you're printing a lot of other info at the end, time taken, bandwidth, etc. That's all very nice. But ultimately for comparing whether each capacitor was better or worse than the others (including the no capacitor case), all that spew isn't needed. What gets recorded for each Capactor-and-Frequency test is just a single number representing the number of failed reads. I don't see that info at the end of all this spew.

Okay, that would be a different test base to get that. So far - with No_CAP - I have something that never fails - or fails on first pass.
The PSRAM test in changing the value 57 times goes a long time quickly compromising the time spent on repeat reading - and

But this test from PSRAM goes through 57 different value tests. The trend is that some fixed values can work even now at 212 - but NONE of the Psuedo Random streams survive for long.

So, the test would be based on a single Psuedo Random series - and then something like that could be done more easily.
Post #168 shows that consecutive addresses don't fail - but certain locations having different number do.
Here for instance, it starts earlier than some but makes headway:

Test:
Write same Psuedo Random values to Lower and Upper 16MB of 32MB SDRAM.
Verify that both read back to expected Pseudo values - or abort with error count
--loop x times
> Read and compare corresponding values in upper and lower halves to match

Here are three results with 20 read compare loops after writing initial values:

This is with 221 MHz failing with no cap - it aborts as it fails on first compare:

PseudoRand(1) Seed 1438200953 with readRepeat 20 ...
INSTANT FAIL pseudo-random sequence written does not match as written in both Halves: Errors Cnt 710

This is with two manually edited values one lower and a diff in upper halves:

PseudoRand(1) Seed 1438200953 with readRepeat 20 ...
Fail pseudo-random sequence not same in both HalfCmp with seed=1438200953
Same pseudo-random sequence in both HalfCmp Compare time secs 6.88 with Error Cnt 420

This completes no errors at 198 MHz

PseudoRand(1) Seed 1438200953 with readRepeat 20 ...
Same pseudo-random sequence in both HalfCmp Compare time secs 6.88 with Error Cnt 0
All memory tests passed

A run of 2000 iterations will takes 623 seconds?

Doing the Psuedo math to compare all 32MB adds 50% to the time and results in the same number of reads, versus this assuring the top and bottom 16MB read and compare.

This shows PSRAM clock freq - not seen ref to clocks to show running SDRAM speed yet?

Indeed that's incorrect. 3 sources are selected by 2 muxes. See the clock tree diagram in the reference manual.
