i need to program the internal flash of this chip.
I am trying trough a simple parallel cable. This is the result:
jtag> cable EA253 ppdev /dev/parport0
Initializing ppdev port /dev/parport0
IR length: 4
Chain length: 1
Device Id: 01001011101000000000010001110111 (0x4BA00477)
Manufacturer: ARM-CORTEXM3 (0x477)
Part(0): AT91SAM3N1A (0xBA00)
As first strange thing i am getting device id as 0x4BA00477, but from the manual i should get another "Atmel" coded.
Trying to read the memory i get :
jtag> readmem 0x40000 12 out.read
error: illegal state: Bus missing
Every help is very appreciated
