angelozip, Neil, It looks like rrgn command is disabled in this boot.bin, but it's enabled in the bootloader.
I've never seen this before, but the bootloader is capable of running update.txt script, though, the exact conditions of doing this are hard to deduce.
After disassembling and comparing the bootloader and the boot.bin a bit I can speculate that it's executed during the "normal" operation cycle of the bootloader.
The question is, what we consider "normal"? Quickly load fw_all.bin and execute it? Or enter pre-boot mode, initialize USB and wait for USB commands?
In order to run update.txt via bootloader I suggest doing the following:
If the above doesn't help, try entering pre-boot mode in step 3.Code:Please Login or Register to see the links
