I've deciphered the htc header format as I couldn't find other information about it. Fairly straight forward:
16 bytes consist of the word GREATWALL in ASCII followed by 7 spaces (0x20) 16 ASCII zeros (0x30) 96 bytes of binary zeros (0x00) 4 bytes as HTCS in ASCII 8 bytes of ASCII hexidecimal (I think this contains the load address it will need further investigation) 8 bytes of file length in ASCII hexidecimal 8 bytes of checksum in ASCII hexidecimal (unknown checksum method) the .bin file to be loaded must end with 4 bytes of ASCII: HTCE Using this I've determined that the kexecboot file in /demos is to long to act as a 2nd stage bootloader for the H2200 or is corrupt (kernel decompresses and generates a crc error). The files needs to be 1,310,720 bytes or less in length (excluding htc header and terminating HTCE tag). Even if the file length parameter is adjusted it will load more of the kexecboot binary into the 2nd stage flash but the 1st stage loader will only load 1,310,720 bytes as far as I can tell (unless, of course, the existing file is corrupt). I don't have a development environment setup. If anyone is already setup for targeting the H2200 could you grab the kexecboot stuff and see if its even possible to make the .bin file smaller? I'll test it if you build it and upload it to /demos (or give me a link to the file). -Matt _______________________________________________ Angstrom-distro-devel mailing list Angstrom-distro-devel@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-devel
