[OpenOCD-user] flash bank for TI cc3200 launchpad

[Christopher H. <ch...@ba...>]

I'm looking at the configuration file for TI's cc3200 launchpad board
that shipped with openocd-0.9. The board has a flash chip with part
number W25Q80BL connected directly to the cc3200's "boot" SPI pins. When
reading the reference manual for the cc3200 I noticed that the boot SPI
port was designed specifically for reading in a program to run on boot
and that it can be accessed directly from the base address of 0x44020000
-> 0x44020FFF. The cc3200 has no internal flash. I was wondering why
openocd doesn't include a flash bank configuration for this board. As it
stands TI's "uniflash" tool is only supported on windows leaving the
Linux community without a means to flash this chip. I'm not proficient
with OpenOCD, but I feel like the cfi flash driver should be able to
handle this case out of the box. I'm not on my development machine now,
so I can't post the configuration I tried, but I was mostly guessing so
it's probably all garbage anyway. If anybody has any insight into how to
configure OpenOCD to read/write the flash on this board please let me
know and I'll post my results, and hopefully fully support this board in
future OpenOCD releases.

Thanks,
Chris
