nrf52840 usb: index out of bounds: the len is 8 but the index is 8

Open vDorst opened this issue 1 year ago • 3 comments

I am trying to create a usb soundcard, first I started with a blackpill stm32f401. But I had issues with sample delivery it was every 2mS instead of the wanted 1mS. So I thought to rule out the stm32 usb stack I port the basic code over to a nrf52820.

But I hit a index out of bounds: the len is 8 but the index is 8 error.

Code: https://github.com/vDorst/stm32_audio/tree/nrf own embassy brach but it is not needed I think: https://github.com/vDorst/embassy/tree/i2s-no-mclk

For the UAC1.0 I only using a usb controll and isoch out endpoint.

can you post trace-level logs?

@Dirbaio here the trace log.

The crash happens when the host wants to send sound samples to the device.

log-level = trace.

I found the issue but I think it is not quick to solve. This comment in the code gives me the clue. iso Isochronous have there own hardware registers. It seems that is currently not supported in the nrf hal.
