Somebody email me this. It said we can upload the boot loader via 232 Null Modem cable. No need for a Jtag. Don't know is it true? Is it possible and anybody tried?
not only that but if you know anything about a bootloader. it is just that it is like the bios of a pc. it tells the flash chip that this hardware is present and the program is located at address x. it this is damaged or destroyed then the serial comms will not work. Jtag is a serial connection between all chips in the box. (if i remember my old school stuff) it has a chip id and tells the flash to overwrite a certain area (bootloader).. if only i could do a full flash this way
