Creality Ender-5 S1
The bootloader on the stock board has special requirements and requires a flag to be set in the EEPROM before it will install the firmware.
- The built firmware bin file must be placed into a folder named
STM32F4_UPDATE
on the SD card. - Connect to the printer over serial and send
M936 V2
. (You can also run a G-code file containingM936 V2
.) - Make sure to always flash a working version of Marlin with
OTA_FIRMWARE_UPDATE
enabled! - If for any reason you can't run
M936 V2
then you'll need to run a sketch to write 0x02 to EEPROM address 90 (e.g., withBL24CXX::write
).
