Crashing on SAMD #35

Closed timonsku closed 4 years ago

timonsku commented 4 years ago

Using SAMD Core 1.5.7 and TinyUSB_Arduino 0.7.1 I can't get any of the examples I tried to work, the Serial port never comes back after uploading and Windows reports a malfunctioning USB device. Tested on SAMD21 and SAMD51.

With just the blink example uploaded but TinyUSB selected it is still working.

I tested generic HID and Keyboard HID. Both crash. I also tried MSC Ramdisk, which shows up after a while and the serial port also comes back but then disappears again after a bit.

BSP and library are probably out of sync, thanks for reporting. I will check it out.

Hi there, also trying to get tinyusb MSC to work after updating the core. Same issue with the serial port not coming back after uploading. This was solved by updating the samd core with adadruit's latest commit. However it is now the SD card not initializing. The example msc_sd works fine but msc_sdfat doesnt: the cards fail to initialize. Edit: Examples from SdFat library dont work either. So I guess it has more to do with the core itself that with tinyusb

@FAksel thanks for confirmation, the core and library is out of sync. For your issue, SD card may not be reliable, can you verify that msc ramdisk and/or msc external flash are working ?

FAksel commented 4 years ago

msc ramdisk works ok. Don't have external flash to test.

It is more a spi problem though as none of the SdFat examples work.

I could solve the problem by reverting the changes in SPI.h brought by this commit: https://github.com/adafruit/ArduinoCore-samd/commit/516cec5a9b927b0890485d76b49508442a85c2cf

@FAksel thanks, if you think it is spi problem , please open a separated issue for it in samd core so that others could look at it.

FAksel commented 4 years ago

Commented PR 186 with the problem. Thank you.

Any eta when they are aligned again? Would like to work with a working "official" combination for an upcoming project.

hathach commented 4 years ago

soon enough, we are doing a re-org https://github.com/adafruit/ArduinoCore-samd/pull/190

hathach commented 4 years ago

TInyUSB in BSP and Library are released and should be in synced, please try again to if that work for you.

Thanks! Seems to be working again with current SAMD and TinyUSB from the Library/Board Manager
