[OpenOCD-devel] Support for CC2538 Flash loader

[Stephen H. <ste...@gm...>]

Hello,

I am trying to program a CC2538 using an Olimex ARM-USB-TINY-H. I can
connect through JTAG, halt the CPU, read and write registers but am unable
to program the flash. I have read through the thread
https://sourceforge.net/p/openocd/mailman/message/35330344/ and get the
same results using the suggested patch from
http://openocd.zylin.com/#/c/3719/

It doesn't appear that the CC2538 shares the same ROM API as the CC13xx and
CC26xx. The TI CC2538 Foundation Firmware (http://www.ti.com/tool/cc2538-sw)
rom header (driverlib/cc2538/source/rom.h) shows a different location and
set of functions than those used in the CC26xx flash driver.

Is there anyone working on implementing a flash driver for the TI CC2538?
If not, this is something that I'd be happy to try and implement.

The cc26xx flash driver (http://openocd.zylin.com/#/c/3719/) looks like a
good place to start. I can adapt it to the cc2538 using the Foundation
Firmware as a guide for how the ROM API and flash should be used. Is this a
good approach?

Thanks,
Stephen Hamer
