Notes for use of SPIM external flash
- For the use of SPIM, the user hast to take care, when setting up clocks, that AHB clock does not exceed 120 MHz.
- When clocks are not setup, J-Link sets core clock to 200 MHz and AHB clock to 100 MHz during SPIM flash programming.
- Only SPIM Type 2 / EN25QH128A is supported right now.
Watchdog Handling
- The watchdog is fed during flash programming.
Device Specific Handling
Reset
- The device uses normal Cortex-M reset, no special handling necessary, like described here.
