Our customer requests to fix SDOCM00092510 and SDOCM00105048.

These root causes describe: "Increased code memory requirements in firmware to implement this support".

Does this indicate that internal memory size of PRU is insufficient to implement this support?

Hi Daisuke, both issues (SDOCM00092510 and SDOCM00105048) has a work-around explained in the errata.
Specifically, for fixing SDOCM00092510, firmware code memory footprint would increase ( it is already pretty thigh) and we believe this configuration doesn't offer a significant benefit (sub-optimal) so currently there are not plans to fix it.

thank you,
Paula
