| Reprogramming needs a STM programmer like this [[https://www.aliexpress.com/item/FREE-SHIPPING-ST-Link-V2-stlink-mini-STM8STM32-STLINK-simulator-download-programming-With-Cover/1823628996.html|one from china]], or if yuo can't wait that long, [[https://www.amazon.co.uk/gp/product/B0722WMDFQ/|this one]] on Prime from Amazon. The Driver for the ST-link-V2 programmer is here [[https://www.st.com/en/development-tools/stsw-link009.html]].

| I then tried for several hours to re-programme the chip, and kept failing, before discovering that I needed to turn off the 'Read Out Protection that was turned on in the chip. I used the STM32 ST-Link utility to do that, connecting to the RS41 (Target -> Connect) and then editing the Options Bytes (Target -> Options Bytes) to disabled Read Out Protection and 'Unselect all' in the bottom 'Flash sectors protection' section. | I then tried for several hours to re-programme the chip, and kept failing, before discovering that I needed to turn off the 'Read Out Protection' that was turned on in the chip.
