Is there any "proper" way for me to discover what device name the kernel uses? I have tried the following command lines without success: 1 - mtdparts=myflash:4096k(allflash),3072k(firmimg),448k@3072k(bootcode),64k@3520k(status),512k@3584k(conf) 2 - mtdparts=physmap-flash:3072k(firmimg),448k@3072k(bootcode),64k@3520k(status),512k@3584k(conf) 3 - mtdparts=cfi_cmdset_0002:3072k(firmimg),448k@3072k(bootcode),64k@3520k(status),512k@3584k(conf) The first one is the one from my previous post. The next ones had the name of the device changed *and* the 4MB at the start removed. Do you want my config file? Do you want any dmesg output?
