RE: [ECOS] RedBoot partition corrupted with bad image

["Bhanu Prakash Adhikari" <bhanua at aztecsoft dot com>]

I believe they are not formatted as I get the error without [-r] flag -

(For loading ramdisk)

RedBoot> load -m xmodem -b 0x800000

CCCCUnrecognized image type: 0x1f8b0808

xyzModem - CRC mode, 2(SOH)/0(STX)/0(CAN) packets, 4 retries

Are you sure that the images you are loading aren't formatted?
e.g. S-record or ELF images?  If they are, you should not be
using the raw flag (-r)
