Thanks Paul - makes my life simpler. Will work on them tomorrow - kind of done for the night now.

Pushed it again -

it didn't push the changes I made - but those errors sounds like SDRAM_t4.h isnt in the .cpp

Closer - No BUILD errors!

But something still a bit off. I saved your sketch above - and it got wiped in the last folder update since I don't have write permissions.

On my sketch now getting:

CrashReport:

I wonder if someone should try some more strenuous DMA testing. The simple code that @mjs513 and myself setup yesterday was pretty simple, and only did some DMA writes to the ILI9488 (and I believe ILI9341) display. And nothing else was going on while that update was happening. I believe that Mike found that the DMA was not working out higher speeds.

Might be good if someone did something like what FrankB was doing with the ILI9341 and maybe read in the next frame while one frame is being displayed. I believe he updated the top half of the frame buffer when the bottom half was being output, likewise for lower half...

Or I believe when we were playing with the MicroMod we had code running that would receive data from camera and update the display.

Or maybe someone could implement a sketch that uses:

GitHub - bitbank2/AnimatedGIF: A lightweight Arduino GIF decoder for playing animated files from memory or files on SD cards

A lightweight Arduino GIF decoder for playing animated files from memory or files on SD cards - GitHub - bitbank2/AnimatedGIF: A lightweight Arduino GIF decoder for playing animated files from memo...

github.com

to read in the different images of an animated GIF and display them... Note several of our display examples we have used his decode of JPEG and PNG files to display on the screens. This would probably be similar.

Obviously even better if you actually implemented the eLCD...

Sorry, I know, just random thoughts.

Good luck

defragster · Jan 6, 2024

@Rezo is getting this DevBoard to work on the eLCD - so he'll have that in a week or so when @Dogbone06 gets the next boards.
He can speak to the use of DMA in his process? And if it does get used we'll know.

@KurtE - if you think it would be fun to play along you might get lucky by saying so ... just instigating ...

@Rezo has made a display board to mount on this footprint IIRC - and that is what he'll be working with.

Need to wash my hands - and then check that I got the right MPU settings in startup.c that could explain the earlier 'data access violation'

defragster · Jan 6, 2024

All is well with Standalone SDRAM_t4 on a TD 1.59 BETA5'ish clean install.

I posted code a while ago that uses the eLCDIF to generate VGA output (using 4-bit color via an R2R ladder): https://forum.pjrc.com/index.php?threads/teensy4-lcdif-sample.72657/#post-324741
It uses double-buffering but one frame has to be in RAM1 and the other in RAM2 due to size limitations....

I also made more or less the same thing using FlexIO: https://forum.pjrc.com/index.php?threads/vga-output-via-flexio-teensy4.72710/#post-326842
This is more flexible and uses explicit DMA, to do things like line-doubling. It could also do higher resolutions with more memory available.

Quick demo of malloc() versus sdram_malloc():
>> Pulled the code - it fails on true MicroMod ... needs NULL check somewhere ???
- all the RAM2 will be gone - should get 0/Null ptr?

Looking at return the sdram_malloc() on true T_MM thinks it has SDRAM when it does not - it is not calling malloc() - but returning SDRAM address space pointers and .begin succeeds?

SUCCESS sdram.begin()
---- MALLOC fallthrough return: 0x9000000c
---- MALLOC fallthrough return: 0x90020028
---- MALLOC fallthrough return: 0x9000000c

Seems SDRAM_t4.cpp::bool SDRAM_t4::SendIPCommand() never returns False with T_MM on DataLogger carrier.

I just pushed up a few examples

Yeah which is scary. Just tested it on a T4.1 and it hangs it - looses it.

On a Micromod

When I looked at the datasheet for the SDRAM I didn't see a who am i register to identify the chip so not sure what to do

mjs513 · Jan 7, 2024

@PaulStoffregen = @defragster
Think I may have a way around it.
If I run the SDRAM_test that I just posted (equivalent to the PSRAM Test) it shows the error

Code:

testing with fixed pattern 5A698421
 Error at 90000000, read 00000000 but expected 5A698421

So will probably include a test like that in sdram.c

UPDATE: Ok added in a test and it worked. Now guess I have to do something to zero out SDRAM and work on the readme

defragster · Jan 7, 2024

I was wondering if the chip had an ident like for the littlefs devices to ask before going ahead with pinChanges and other.
Will any of those pin changes undo the few T_MM pins under the SDRAM?

That was the thought here that a quick safe content seems the only way to revert to malloc() as long as the pinChanges didn't corrupt any initial pin settings in analog_init(); or pwm_init(); ?

Perhaps a user should abort when no SDRAM after trying the .begin if the changes affect other Arduino named pin function? Of course just not using on those without SDRAM seems easy enough.

mjs513 · Jan 7, 2024

Here’s my thought. If a teensy doesn’t have a sdram they shouldn’t be incorporating the library to begin with. Remember this is a library and not part of the core.

As conflict with tmm could be but don’t think core will be officially changed to support the dev board. We would have to do it locally.

Can’t even put a ifdef on a board because we don’t have a teensy version that supports sdram.

Maybe Paul needs to address the issue about the pin changes.

defragster · Jan 7, 2024

@mjs513 - seems all your changes may not have propagated again? I had to add the pattern test to the class and then it isn't working to detect on real MicroMod ... but does fail over when SDRAM exhauted on DevBoard:

class SDRAM_t4 {
public:
constexpr SDRAM_t4() { };
static bool begin(uint8_t external_sdram_size = 32);
static bool check_fixed_pattern(uint32_t pattern);

From pulled test code on DevBoard where some RAM2 remained it got allocated:

...
---- MALLOC fallthrough return: 0x91fc1bd4
---- MALLOC fallthrough return: 0x20223090
SUCCESS SDRAM malloc
SUCCESS SDRAM 256 * 128KB initialized

1 RAM2/DMAMEM compares of 1
256 SDRAM compares of 256
Addr reference: RAM1/DTCM @0x20002258 : RAM2/DMAMEM @0x20203088 : SDRAM @0x9000000c
Complete

On the MicroMod with went to fault.

PaulStoffregen · Jan 7, 2024

Agreed, SDRAM_t4 is for people who have made custom hardware. They know which chip is on their board.

Of course you should write whatever code you feel is interesting or fun. If you want to implement special hardware detection, don't let me talk you out of doing something you're interested to do.

But if you're looking to wrap this up without spending a lot more time and you want my opinion, besides my feedback in msg #307 (much of it already done), I'm really hoping you'll eventually publish on the main branch.

mjs513 said:

I consider changing pin mapping to be a separate matter concerning all custom boards, only coincidentally related to SDRAM. Of the many things I might do, this one is a pretty low priority which for all practical purposes means I'm unlikely do to anything with it soon.

defragster · Jan 7, 2024

Sounds good here as it isn't a PJRC product issue. Just went to test that simple sketch that seemed would be safe and then it went so wrong crossing into known failure case.

Okay that is the same change I made locally to get the build - though somehow the mem test or something failed and 0x9--- addresses still returning on true MicroMod as used.

Though just tried exmaple\SimpleAlloc.ino and it acted properly: SDRAM Init Failed!!!

mjs513 · Jan 8, 2024

@defragster
That sketch is outdated. New example sketches created:

If you run the SDRAM_MALLOC sketch (equivalent to the simple_alloc.ino file) its working fine for me.

Code:

Entered number of elements: 24
Memory successfully allocated using malloc.
The elements of the array are: 1, 9000000c
2, 90000010
3, 90000014
4, 90000018
5, 9000001c
6, 90000020
7, 90000024
8, 90000028
9, 9000002c
10, 90000030
11, 90000034
12, 90000038
13, 9000003c
14, 90000040
15, 90000044
16, 90000048
17, 9000004c
18, 90000050
19, 90000054
20, 90000058
21, 9000005c
22, 90000060
23, 90000064
24, 90000068

Try running SDRAM_test (equivalent to memtest) - that had to be updated. That works for me as well.

Just pushed to the main branch along with an updated readme. Leaving the working branch there for now.

(much of it is already done...

not sure what else needs to be done now?

defragster · Jan 8, 2024

Was there a switch back to Main branch? CROSSPOST ...
ReadMe.md said I changed and merge conflict resolution confused it ....

Still getting error with the MultiRamCmp example - may be on old branch to see?

Yeah I just switched to main branch and I resolved the merge issue when I incorporated the PR.

"MultiRamCmp" example - where is that?

EDIT: of found it - you must have just pushed it? otherwise it would have been up on main.
