I miss this point, what is wrong with that? It seems I thought itself :-), you have to see both those keys, because the RedBoot config is (flash_config.h) struct _config { unsigned long len; unsigned long key1; unsigned char config_data[MAX_CONFIG_DATA-(4*4)]; unsigned long key2; unsigned long cksum; }; I did try to say what that point checks just 3 things: CRC, KEY1 (0x0BADFACE) and KEY2 (0xDEADDEAD): if ((flash_crc(config) != config->cksum) || (config->key1 != CONFIG_KEY1)|| (config->key2 != CONFIG_KEY2)) { diag_printf("**Warning** FLASH configuration checksum error or invalid key\n"); diag_printf("Use 'fconfig -i' to [re]initialize database\n"); config_init(); return; }
This is my printf result just before the if test config->key1 = 0xbadface, config->key2 = 0xffffffff, config->cksum = 0xffffffff, flash_crc = 0x706de31e As you see I don't get config->key2 and config->cksum with the right values.
Check what that KEY2/CRC is present at the end of 4K area.
I can't find it. I don´t have any KEY2 at 4K area.
You believe that CRC is okay. So, this is the last point. Try to
build a minimalist
RedBoot, i.e. which supports serial and Flash devices only. That reduces a size of RedBoot and rebuild-time. That will be to have a few config options. I wonder it's possible 'fconfig' issue won't be occur... So, try to remove NET stuff from RedBoot:
After investigate more and more I think I have a problem with sectors configuration in flash. I read am29xxxxx_parts.inl and the support for the part number I have in my board (S29GL064MR3) doesn't look fine. The sectors seems to be wrong since it is just TOP boot and not top/bottom as described there. I will try to do some changes tomorrow.
ecosconfig new <your target> redboot ecosconfig import <your ecm file> ecoscongig remove CYGPKG_DEVS_ETH_POWERPC_FEC ... ecosconfig resolve make Well, I don't know your target stuff, so, look on top your own ecos.ecc file to know which NET* related packages (Eth I/O drivers, DNS client, etc.) you can remove, and try to build such a minimal RedBoot image. Will you get 'fconfig' warning with the minimalist RedBoot? If you will... I have no more ideas, sorry :-(.
I hope don't get at this point ;-)
