Trouble using USB OTG on SABRE for MFG Tool

Hello all,


I want to copy my uBoot and Android distribution into the eMMC of a imx53 SABRE tablet, with the MFG Tool.


- I've changed my SW26 (0x00) and SW28 (0x30) dip switches to the according value for USB Serial Download Mode for the MFG Tool.

- I've connected with the OTG port (J34) micro-USB connector on the tablet side, following the Freescale BSP user guide.

- On the PC side, I have a Windows XP SP2.



The issue is that the tablet is not correctly recognized by the PC. A peripheral is enumerated, but no VID and PID declared. So I'm unable to match it with the iMX_BulkIO_Driver.



- I'm not sure about the use of the USB OTG port use. Is this the right one ?

- Did I miss a step ?

- Which other way do I have to update a bootloader, kernel, ramdisk and partitions on the eMMC ?


Thanks for your feedback and help.


Best regards,
