I'm using OpenOCD with a combination of JLINK (Segger) and LM3S2412 board. That's working fine.
However I want to access an external NOR flash (SST25VF032B) with OpenOCD. Here is my config:
Code: Select all
source [find interface/jlink.cfg] set CHIPNAME lm3s2412 source [find target/stellaris.cfg] set _FLASHNAME $_CHIPNAME.SPI flash bank $_FLASHNAME cfi 0 0 1 1 $_TARGETNAME jedec_probe
but would expect that the JEDEC ID would be read anyway.
Does anybody know if it's generally possible to access external NOR flash via MCU (Cortex-M3) ?
