3530 ES2.1 silicon support

DavidVescovi

I have noticed after upgrading many of our units in the field they no longer boot from the SD card.

The xldr seems to initially start but fails when trying to bring in eboot from the card.

These units were originally built to the 6.13 BSP and upgraded to the A8_01 BSP.

All the failed units have the 2.1 silicon so I suspect the multi-block read bug to be the issue.

It looks like there was an attempt to implement the workaround in the BSP but I do not believe it is complete nor does it work.

Is it true 2.1 silicon is not supported in the new BSP? Was any testing done with previous (2.1 or 3.0) silicon?

Release notes specify what HW Rev was used for testing. To answer the question directly, no we don't test the BSP with 2.1 or 3.0 silicon as these boards are no longer available. It is possible that recent changes may have broken something for older silicon but this is something that you will have to (unfortunately) debug.

thanks

David,

I attached a modified version of oalcpuver.c. It is my wild guess of the problem. If you think it makes sense, you can try it out.

Thanks,

Actually it took a little more.

Seems the 6.13 boot loader code was modified and now A8_1.0x requires multiblock reads ...which ES2.1 can't handle.

I did a silicon version check in the boot loader version of sdcard.c and now do a single block or multiblock read.as needed.

Seems to work great.

Attached is the modified file if anyone is interested.

I have not looked at the OS level driver yet to see if it also has the same limitation.
