TMS570LC4357: Occasionally fails to detect that the mibspi's RXEMPTY flag == 0.

dai dai

Part Number: TMS570LC4357

Tool/software:

When using mibspi in master mode, not utilizing interrupts. After configuring and initiating the RX RAM transfer, I use while (rx_ram.RXEMPTY (flag bit 31) != 0) to detect whether the reception is complete.While this approach works effectively in most cases, there are occasional instances where the RXEMPTY == 0 state persistently fails to be detected.

I have noted the entry MIBSPI#139 in the errata manual: "Mibspi RX RAM RXEMPTY bit does not get cleared after reading." However, the issue I am encountering appears to be related to the RXEMPTY flag not being set to 1 promptly. Additionally, no other transfer groups have been configured in my setup.

Hi Dai,

Is it possible to setup one live debugging call? Where you can share your screen and can explain me issue in detailed.

This would be helpful to understand the issue clearly because i never saw this issue before.

I will be available from 10AM to 8PM IST (Indian Standard Time), based on your availability you can setup a meeting.

Hi Dai,

The reason for unlocking this thread is that it is not closed properly from TI side, so i unlocked it again.

Apologies for the incontinence.

Are you still stuck with this issue, if yes then please let me know exactly where you stuck with this now.
