Good Morning Paul (and all), If you are following the MassStorage... thread, you probably have noticed a few comments about corruptions of lists. Yesterday I did find a very possible set of conditions that maybe...

Note: most of the cases that this would hopefully fix are those that are initiated from the user code. Like: please write 4096 bytes to the file... Things like Reads are mostly handled by first doing the queue out of...

Installed W11 using IDE 2 todays nightly build. Ran a couple of tests. So far so good! Will try on Ubuntu although I think my hard on that machine is toast and/or the install is.

Thanks @mjs513 I have also run a few more tests. Will try some more. So far not noticing anything.

Note: I just pushed up a new fork/branch: https://github.com/KurtE/USBHost_t36/tree/queue_transfer_protected Where I updated: bool USBHost::queue_Data_Transfer(Pipe_t *pipe, void *buffer, uint32_t len, USBDriver...

Sounds good. I am playing a little with the USBHost stuff, to maybe plug a few more possible data corruption possibilities. For example, in RAWHID you do a sendPacket It simply calls through to the HID code:...

Again it is sort of on a case by case basis. For example already within: the USB Serial code. I know that: the ::write method, may queue a data transfer. But it already protects itself, by disabling the USB interrupt...

Good catch. Have you changed it to see if it makes any differences? Can you issue a PR back to @PaulStoffregen and maybe get it into the up coming release? Not sure if he would pull it in or not or if he maybe is...

Maybe not... But maybe some/all queue_data_transfer calls need to be protected. For example maybe add optional parameter to queue... like: static bool queue_Data_Transfer_Debug(Pipe_t *pipe, void *buffer, ...

Sorry, been busy doing things like sleep ;) Wondering if some of this in Midi is also a red herring, or symptoms of other problems... Here are some random thoughts, on things to maybe look at, or try to see if we...

Building for USB type - midi Does it work? Note: I know almost nothing about midi, nor use it at all. But tried opening the TransmitEverything.ino example sketch on a couple of day old Arduino 2 nightly build....

What USB type are you building for?

I don't have much of anything: Audio library, there were two different PRs to allow one to play a wav file from all Filesystems, not hard coded to SD... Again not overly critical. Cores: Looks like you have...

Hard to really know what is going on. As we may not know the whole setup including the setup code, what else is connected... But code too large: you would normally think that would behave the same for reboot versus...

@Garug - not sure here... Especially if for example your Arduino 1.x version and 2.x version are both running the same version of Teensyduino code. Then I would think they should give you more or less the same...

@yeahtuna Quick thing on your sketch, which may or may not help. On the second teensy, it logically looks like it boils down to: void loop() { myusb.Task(); if (rawHIDTimer > 50) { ...

Sorry, there is not much of checking in this code. Like most of the commands in that sketch, it runs off of the currently selected drive. SO in Command prompt after comes up if you use the 1 command 1<cr> It will...

If you are curious about MTP: The main document I look at when doing this, can be downloaded from: https://www.usb.org/document-library/media-transfer-protocol-v11-spec-and-mtp-v11-adopters-agreement This gives you a...

@wwatson @mjs513 @defragster and all I hacked up the USB_MTP-logger.ino sketch and added a write file test. Pretty primitive: void test_write_file(int ch) { test_file_write_size = CommandLineReadNextNumber(ch,...

You are right... For awhile, I did not see ones from some libraries I have worked on... like FlexIO... But it is there now Thanks

Sorry, I am just trying to be pragmatic here and go with the flow. As I mentioned, I have tried to keep things within the ways that Paul has used in some of these areas. And with the case you mentioned, tried to...

Again I am not a MAC person, but have pulled mine out of the cupboard, and going to update it now... was 2.0.3... Easy parts: What version of Teensyduino are you running? With Arduino 2.x: You can see it a...

I understand what you are saying, but at least in many of these cases it may depend on who and how these methods are called. For example if you look in Serial.cpp, where the txTimer is used. Whenever we start or...

Maybe one of us (me?) may have left a debug line uncommented. Look in the USBHost_t36 directory. And look in hid.cpp for: void USBHIDParser::out_data(const Transfer_t *transfer) {...

I am still sort of curious on the speed of these drives: So put an elapsedMillis into the sendObject code, and at the end (debug >= 1) printf("SendObject complete size:%u dt:%u\n", size, (uint32_t)emSendObject); ...

It works on mine: Note: if it does not work, try to make sure it is trying to write to the Teensy port code and not the generic Arduino port code. You should see it in the tools menu: Also should make sure...

Personally I would only send one device reset event, after you have changed the file or file(s). What it does is it tells the host to end the current session, the host will send MTP a new begin session, at which...

Note: As for the not seeing the last lines... There was a fix since the last released version. You can download from the main arduino.cc software page. As mentioned there are still many issues with the Serial...

Again I don't use the MAC, except at times for MAC specific issues. I mostly use Windows (main machine has W11), secondary machine Ubuntu 22.04 (or W10)... Note: At times I think of Ubuntu in the same way that Paul...

Note: you will never exit the line: while (1) yield();

Quick update: The problem child (SDCZ73-032G-G46) that "works now" https://www.amazon.com/dp/B01FTQP7ZM?psc=1 I was able to transfer a 6.44mb file to it, but it took probably over a minute to complete. As...

Note: I am not much of a MAC person, but have older MAC laptop that I use to debug stuff on from time to time. On it I was using some version of MTP like you mentioned, that had a 10 day trial period... But then...

@wwatson @mjs513 - I tried the change and as mentioned it appears to fix the issue with at least the problem child I picked up. I ran the MTP USB example and was able to both have it create the log file on the drive. ...

Did the udev rules get installed

Sounds like something to try. I have seen the clear feature like this somewhere else.

@mjs513 @wwatson @PaullStoffregen (if you are watching) - thread shows last look about a week ago. Some of this lower level USB stuff is above my pay grade (of $0) ;) Stalls - I have looked a little bit...

Another simpler option for you maybe to try: That is if you call begin() before it is there, maybe we should still try to use that baud rate when it does connect: If you go into the USBHost project sources on your...

Strong guess, FTDI cable is buffing the stuff... If you output your 82 bytes to userial1 and then do userial1.flush(); Does it work? My guess maybe not. The cable probably has some logicai IOCTL that tells the...

Sorry, it has been awhile since I looked at the USB Host Serial code. I think there is sort of a chicken and the egg problem. It does appear like the code does default to 115200 when the object first connects. ...

Sorry I am not sure exactly what you are asking, So will try to give some generic information. The Serial object, tries to fill up a USB buffer and then sends a USB packet to the host. Things that control how USB...

Will have to take a look at those. But first I am curious about the failure: File "annie3 - Copy.bmp" size:230454 Created:641d6f21 Modified:61e3a02e read consumed all data (TODO: how to check ZLP)...

Yes those are the ones. The ones that grow maybe near an inch wide, and maybe 50' long, with long sharp thorns... These gloves help:...

Any luck on this yet? I will try to take another look soon. Right now doing fun things like: cutting Himalayan Berry vines out and chipping them.

For me, the AD_B1_ is the pin name, the GPIO number is closer to the PORTA, B, C, D of the AVR processors. For example if you look at my excel sheet in GPIO pin order. You will see a column with name... the AD_B1_...

Quick note, I picked up my delivery of 4 of the Sanddisk ulta Flair 32gbs... Looks more or less identical to what @mjs513 showed yesterday... I did also try reformatting it on PC to FAT32 and no differences. MTP...

Many/Most of the HID drivers keep a back pointer to the USBHIDParser object. This is passed to you in the claim_collection method. Many use it to restrict their object to only dealing with one HID parser. And...

Sorry, I am distracted as I am trying to debug some of my own not related code. Count of devices really only impacts as you mentioned amount of memory. And maybe in few cases where it walk the list of objects.

Probably. It is probably with the DNS that I am using. I think I still have it hard coded at my connection to my provider as something like: 1.1.1.1 Or might have been googles: 8.8.8.8 Was earlier having problems...

That is the normal way the HID parser code works. However there is a hook that some of the client code, like the RAWHID and for example some cases the Keyboard and maybe some others use. That is, when the message...

Sorry, I was not doing much monitoring up here yesterday... Sort of off doing different things. I have found with some of the Wireless Mice or keyboards, that yes, they can consume several objects. For example,...

I am wondering if this display has a display driver chip on it or if it might be something like the KeDei display we were playing with a few years ago. Which was another RPI 3.5" display, but it did not do standard SPI...

Is there anything that we should be looking for? That is, was this a "simple" server change or was there other things that changed as well? My guess is simple is never simple! I noticed recently that you...

As mentioned, it shows up in current FIrefox on windows 11: But not with Edge. Also looks fine in Adobe Acrobat.

I ordered the other one…

Note: I am a software guy... But.. If you look at the T4.1 schematic it shows a voltage regulator that in main part says range up to 5.5v, but in the spec part it says absolute max 6v. So you might be able to live...

Yes you should be able to do 8E1. Don't remember if you need to enable 9 bit support within HardwareSerail or not, probably not. By default, the support for 9 and 10 bit and more is disabled within the source code...

Sorry, I missed seeing the DMAMEM on your example. To me, the keyword DMAMEM translates to, almost the worst place to do DMA ;) External memory can be worse :D The issue: These areas of memory are configured to...

Paul has a github project to track issues about the website. Did a quick look, and sure enough, I opened up an issue about this, about a year ago: https://github.com/PaulStoffregen/Website_Updates/issues/26

Side comments to self: Part of the write9 code that currently runs, I have wondered if it still fails at times: while (tx_buffer_tail_ == head) { int priority = nvic_execution_priority(); if (priority <=...

My first try would be to add call: dma_ch1.clearComplete(); right before you the dma_ch1.enable();

Do you have any links, for example on Amazon for some of these drives? Preferably ones that are pretty cheap?

Sorry, I am not sure who the "maintainers" are? The only person who can merge in any changes to this library is the Paul. @wwatson, who did most of the original MasStoreage work, has been very active on this...

In case anyone has not noticed: Arduino released version 2.0.4. A few days ago. I have not had any new issues with it, but have seen some reports up on Arduino forum, where some people have run into issues, like...

Couple of thoughts here: I have had times where the crash is very near to startup code and kept in an endless beep reset, beep reset. So sometimes I put code in like: if (CrashReport) { while (!Serial &&...

If you are going to muck with the register, I would do it right after you did any/all SPI.begin() (including SPI1 and/or SPI2...) as they all use the same underlying clock. Note: the code was setup to try to avoid...

Note: The SPI library is setup to allow you to choose a different Clock setting for base of it. It is all controlled by the clock register: CCM_CBCMR Which the SPI library inits each time you call SPI.begin()...
