Hi everybody!
I’m trying to program the ATSAM4SA16C with openOCD. I’ve used the following configuration file:
source [find interface/cmsis-dap.cfg]
# chip name
set CHIPNAME ATSAM4SA16C
source [find target/at91sam4XXX.cfg]
set _FLASHNAME $_CHIPNAME.flash0
flash bank $_FLASHNAME at91sam4 0x00400000 0 1 1 $_TARGETNAME info
set _FLASHNAME $_CHIPNAME.flash1
flash bank $_FLASHNAME at91sam4 0x00480000 0 1 1 $_TARGETNAME info
adapter_khz 250
init
targets
reset halt
program file.elf verify reset
exit
which fails with the error
Error: Flash controller(1) is not ready, attempting reset
Error: flash controller(1) is not ready! Error
It seems to be a problem with my second flash bank.
I’m using the same config file, but now with the following commands (to narrow down on the problem):
flash info 0

Which is OK, but the following is not OK:

I’ve checked the datasheet of the chip, which tells me indeed 2 flash banks exist on address 0x400000 and 0x480000. I’ve also checked the control addresses of these chips in the OpenOCD source, which are also correct (0x400E0A00 and 0x400E0C00)
The result of the last command, executed with “-d3” is found here:

Any ideas?
