hello. i have a board with a ibm ppc processor 4xx and a flash amd160lv, and i have
acess to read this memory using a simple jtag and de flash programer by Mcgraigor systems
My problem is write in a flash!!
In the datasheet of the ep405pc on table 7.3 i see this
2 R/WGFWP 0 = local FLASH is write protected
1 = local FLASH is not write protected
so if you see the datasheet i need to change the second bit on adress of de bcsr2 register
for write a .s19 on the flash, so i need help.
Anyway a need to find the register in a datasheet who protect de checksun verificacion.
