TMS320F28388S: USB IP Fix?

Ed Sanders

Tool/software:

Greetings,

According to the errata, SPRSP14E, the USB HW produces "Inadvertent extra DMA requests". It also states that there is no workaround at the time of the document's publication. So two questions:

1. Is there now a workaround for it, and if so, where can I find it?

2. Will there be a new version of the silicon which fixes the issue, and if so, is there an expected date for availability of the new parts?

Thank you,

Ed,

Sorry for the delayed response.

This errata does not have any workaround . It is a hardware issue where the DMA was not properly integrated with USB FIFO and there is no new version of the silicon with this fix.

Best Regards

Siddharth

Hi Siddharth,

Sorry for my delayed response.

Is there a plan to fix the HW in a newer version of the chip?

Thank you,
