RTOS/TM4C1294NCPDT: SPI status

JHi

Part Number: TM4C1294NCPDT

Tool/software: TI-RTOS

I can't find from source codes SPI.c and/or SPITivaDMA.c anywhere that the SPI_Status bits would be set as described in http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/tirtos/2_20_00_06/exports/tirtos_full_2_20_00_06/products/tidrivers_full_2_20_00_08/docs/doxygen/html/_s_p_i_8h.html#a913c57c335166de9caa54b7eb9ad95fb . The status is always SPI_TRANSFER_COMPLETED. Am I missing something or is this not really implemented?

Hi

First of all, please use the 2.16.01.13 version for TM4C devices. TI has an open bug report on this issue for the TM4C devices:

TIDRIVERS-724: SPI drivers should set transaction status
The Tiva SPI driver does not set the SPI_Transaction status field. This field is documented as a return value so the caller can check on the transfer status.

Unfortunately we don't a new release currently scheduled in the short-term road-map (e.g. next couple quarters).
