TMDXEVM3358: How to boot from USB0

Alankar Dhobale

When i power AM335x EVM with SYSBOOT[4:0] set as 01001b, Windows detects it as "SUBARCTIC" device, but Windows is unable to load the driver for it

I am using Windows XP, i tried loading RNDIS driver which comes with Microsoft ActiveSync, but it fails, and windows pops "Cannot install hardware" message...

Any driver for "SUBARCTIC" or generic RNDIS on Windows XP?

Anybody successful in using AM335x to boot from USB0 (as given in ref manual section no.26.1.8.6), basically i want to load a code in internal RAM, which can be used to program the NAND flash.

i tried to boot from UART0, and it works but i can not use it for production as it will be slower to load bulk application code to NAND through serial interface, and regarding Ethernet boot, there will be some products which do not use Ethernet while production and end application, so only option remaining is USB0

Please help...

There is a ROM code bug that prevents USB boot operation. We will publish more information related to this issue in the next revision of the AM335x Silicon Errata.

Hi,

I would appreciate if you would clarify if there is any possibility of a workaround for this issue. I note that the Errata has yet to be updated, and we need to make a decision whether to modify a board to get around this issue.

Regards,

Stuart
