Re: My own boot loader! (Or others with some help ;-)

2005-12-15 by kibobo59

I have disassembled this file:
bootloader_update_ver_1_52_LPC_2104_2105_2106.hex

within lpc2000_bl_update.zip.

And I want to load in RAM (through JTAG) the code able to write in the
last sector.

PS: debugger is work in progress, further informations soon.
