Fixes

• If you see Zephyr blinky builds and flashes, nothing blinks; program counter at z_SysNmiOnReset, SYSCTL.NMIIIDX reads 6, pulse nRST after the DSLite flash (mspm0_board_reset in OpenOCD); the image then runs (portability/arduino/zephyr/README.md, 2026-10-25).
• If you see Zephyr prints FLASH: 256 KB and RAM: 64 KB, size a Zephyr application for 256 kB flash and 64 kB RAM.
• If you see adc12_internal_temp_sensor_mathacl prints about 507, treat the raw code as relative; cause unknown.
• If you see UART0 loopback PA10 to PA11 fails at 5.5 and 6.0 Mbaud, sends nothing at 12 Mbaud, use 9,600 baud to 5.33 Mbaud or 6.4 to 10.67 Mbaud, and test your exact rate.
• If you see a Zephyr peripheral pin stays low (or does the wrong thing) although the peripheral runs, for example PWM on PB27, define the pin group yourself from SysConfig's MSPM0G351X.json.
• If you see Zephyr main on this board: a second interrupt edge mode on a pin fires on both edges, and PWM duty comes out inverted, clear the pin's two polarity bits before attaching; write period - pulse.
• If you see the first I2C transfer to the Waveshare panel's FT6336U fails right after boot, hold the reset low 5 ms, release it, wait 400 ms before the first transfer.
• If you see an I2C read returns the ID, then the next write never completes and the bus stays busy, leave the ACK bit off on reads so the controller sends the NACK that ends them.
