[U-Boot] U-boot with USB storage support for WonderMedia WM8505

[Chris Barnes]

Hi Albert,

It would be great if i could get the original u-boot image and/or sources
and maybe even the original Windows CE 6 from the manufacturer, however I
dont know who the manufacturer is.

I cant find anyone who makes "Easy Notebook P701" or offers downloads for
it.

These netbooks appear to be mass produced as oem units and rebranded by
numerous different sellers. for example, my netbook also matches the
hardware description of the EPC 7" P701 netbook, and even a netbook called
the Fashion 7" Netbook.


The other issue is that this netbook has been tampered with as far as the
warranty and support is concerned since the previous owner attempted to
install Android which has replaced the wload, the u-boot, and the original
Windows CE system cant be booted anymore so the store the netbook was bought
from wont help.



At this stage i really have no other choice but to take a chance and hope
that someone with similar hardware can provide their working u-boot.

Theres a lot of reports of users attempting to install Android on these
netbooks and ending up in the same position im in but so far ive not seen a
suitable solution. A lot of attempts to fix the problem involve installing a
different u-boot, which ive attempted, but none of them appear to have usb
storage support and therefore the flash disk is unavailable.


My last resort is to go back to the online store where the netbook was
originally purchased and ask someone on their forum if they will be kind
enough to let me copy the u-boot from their working netbook.
