Hello,
We've identified the following bug in the PRU_IO driver, could you please add the proposed fix to the next SDK:
Affected file:
mcu_plus_sdk_am64x_08_05_00_24\source\pru_io\firmware\common\icss_constant_defines.inc lines 147 to 153, the bug affects only operations of PRU1:
.if $isdefed("PRU0")
PRU_DMEM_ADDR .set ICSS_DMEM0_CONST
PRU_CROSS_DMEM .set ICSS_DMEM1_CONST
.else ;PRU1
PRU_DMEM_ADDR .set ICSS_DMEM1_CONST
PRU_CROSS_DMEM .set ICSS_DMEM0_CONST
.endif
Replace the 7 lines with just:
PRU_DMEM_ADDR .set ICSS_DMEM0_CONST
PRU_CROSS_DMEM .set ICSS_DMEM1_CONST
Reason: for PRU1 the memory to use is also ICSS_DMEM0_CONST as the hardware already points to the correct location.
Regards.
