Hi,
has someone ever tried to work with OpenOCD and the Ethernut3 board?
Especially programming the FLASH?
Ethernut3 has an AT91R40008 ARM7 controller an an external
AT49BV322 FLASH chip.
I think it should be possible with the CFI mode?
Any config files, flash algorithms ect. around? :roll:
Greets,
Joerg
With flash probe I get:
Error: cfi.c:1061 cfi_probe(): cfi primary command set 2 unsupported
I think this comes from the wrong CFI command set ATMEL is using?
There were some patches for ATMEL flash around?
I use the following config:
flash bank cfi 0x10000000 0x400000 2 2 0
Regards,
Hello Joerg,
CFI command set 0x2 isn’t supported yet.
You can find patches (well, links to patches) for the AMD/Spansion/Atmel/… command set in this forum (use the forum search, don’t remember which thread(s)).
Regards,
Dominic
Using the latest Subversion check-out seems to work fine here.
