I used IMX_MFG_TOOL to program nand flash for i.MX28.
Connected - i.MX28 EVK Board Connected using USB-OTG to PC. PC detected it as HID complaint Device and i am successfully able to
update the nand flash using IMX_MFG_TOOL. Now, when i connect my customized i.MX28 hardware Board (similar to EVK Board), PC detects it as
Unknown device though i use same device driver supplied in IMX_MFG_TOOL software.
I followed these steps (on customized hardware),
- Selected Boot Mode as USB (iMX28_BSP_UG.pdf- http://elk.informatik.fh-augsburg.de/gnublin-cdrom/Linux/L2.6.35_10.12.01_SDK_docs/i.MX28_Linux_BSP_UG.pdf PageN0.- 3-21, Table 1. Boot Mode Values).
- Connected USB-OTG in device mode to PC.
- Updated device driver (PC side) with the one supplied in software package - Mfgtools-Rel-1.6.2.042 from freescale.
Result - PC detects my customized board as Unknown device.
my question is am i missing any step or configuration, which is there in EVK Board and not on my customized Board, Or is it something else?
Any help would be appreciated, Thanks in advance.
