Thank you James and Min Ling for the eb40a angel images. I wrote a small flash erase tool to erase those lower sectors of the eb40a's flash which I couldn't do with the redboot image I had running in the upper half of flash because the flash driver I wrote ignored those smaller sectors. So I used the redboot ROMRAM in the upper half of flash to upload my flash erase tool and cleaned out the lower half of the flash chip. Then I converted the Angel binary into an srec and loaded it with redboot. Burned it back into the lower half of flash and my eb40a is fully functional again. I think I keep those Angel images and my flash erase tool around though.... -tim On Thursday 25 July 2002 12:37 pm, James wrote: > I have sent to you directly the binary so as not to hog > the mail list bandwidth.
