2010-10-13 15:28:57 Bad data CRC/Can't get kernel image
T. Jump (UNITED STATES)
I've read several posts on this topic (as I am having this issue). I've reviewed TFTP server issues and checks but I'm not having success checking the file sizes with crc commands on my BF537 platform. Also I'm not having success running cksum or md5sum on the pc side as it just seems to process forever and never return any data.
I also saw a post on a patch (see here... blackfin.uclinux.org/gf/project/u-boot/scmsvn/?action=browse&path=/&view=rev) but I'm not sure whether this applies to my particular situation or if the u-boot.ldr I'm using already has the patch applied.
Here is the return I'm getting:
EEPROM @0x0 read: addr 01000000 off 30000 count 2097152 ... done

Help is appreciated.
