RTOS/AM5728: FatFS console project crashes

Part Number: AM5728
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

Hello,

I discovered that the FATFS_Console_idkAM572x_armExampleProject of the SDK-RTOS-05.03.00.07 crashes when inserting or removing the microSD-Card. This happens when booting from the SD-Card directly as well when executing the demo from CCS and the XDS560 debugger.

The idkAM572x.ccxml:CIO output is:

[CortexA15_0] ti.sysbios.knl.Semaphore: line 300: assertion failure: A_badContext: bad calling context. Must be called from a Task.
xdc.runtime.Error.raise: terminating execution

The crash happens in the "AppGpioCallbackFxn"

Do you have a suggestion how to fix this?

Thanks a lot for your help,

Bernd Sprenger

Hi,

Thanks for the info! I was able to reproduce the issue. It may be that the GPIO callback is not a task and inside the GPIO callback there are FATFS_open or FATFS_close calls, it has some semaphore operation which needs to be done in a task content.

I opened a ticket for this.

Regards, Eric

Hi,

We plan to fix this issue in PRSDK 6.1 (end of 2019 Q3), I am closing this issue for now.

Regards, Eric
