Thanks, Brad, for a quick response.
We have purchased 2 Zoom Dev Kits from Digikey, and they both have the same issue with the Linux Demo Disks. I booted into Logic Loader and mounted the Linux SD card using the command
"mount fatfs /dev/sdmmc0a /sd"
This mounts successfully, and the 5 files are present on the SD card, as described in the documentation. Yet, LoLo complains that it cannot find u-boot. The "U-BOOT.BIN" file is on the card. I attempted to load it using LoLo "LOAD" command
"load bin u-boot.bin"
But this fails with the error message
"error: load: file is not in Microsoft NK.bin format (u-boot.bin)"
Please advise,
Greg
