SPI transfere stucking problem

Hi,

I'm using TI-RTOS version "tirtos_tivac_2_10_01_38" and i migrated to "tirtos_tivac_2_12_01_33" and compiler v5.2.4 for TM4C129 controller that run on the DK129.

i have many devices on the SPI interface and i'm using SPI with DMA for TIVA, but i noticed that for unknown reason the processor is stucking during sending for no reason, and i noticed that this version of the TI-RTOS has the following fix,

SDOCM00114670

S2 - Major

SPI driver for Tiva is spinning in the hwi for TivaC but not for snowflake

So, is fix generating another problem?

also i noticed that the task which is responsable to do the SPI transfere is blocked on unkown!!!

Thanks,

Hi Mohamed,

Can you try the SPI loopback example with tirtos_tivac_2_12_01_33 and check if it works on your board? The bug you refer to is not related to this board.

Hi Vikram,

actually i can't run the loopback example on my board as if there is a chip connected to the controller, and my time frame is too limited, so i went back again to the older TI-RTOS "tirtos_tivac_2_10_01_38" and my code it working proporly for the time being, anyway, i will try to investigate more later.
