EZBoard – Flashing Firmware MicroSD Recommendations
Some larger MicroSD cards have been reported to not work correctly for flashing firmware on the EZBoard. If you are using a card 16GB or larger you will want to try a smaller card if the below recommendations do not work. Below are the recommended settings/format/guidelines for making flashing quick and painless.
Guidelines and Recommendations
- Use a small card. Smaller the better.
- You can use up to a 32GB for Gcode but for flashing you want it to be a small card if you are having issues with the 32GB.
- It MUST be formatted as FAT or FAT32
- Try re-formatting the card in case of the card being corrupted
- Have a large card? Try this guide from EASEUS.
- It MUST only have one partition
- If you used the card for something like Octoprint in the past you will need to erase all the partitions on the card and make one primary partition.
- Format that one partition as FAT or FAT32 for the file system
- Here is a guide on using diskpart to clear out a card. Make sure to select the SD card and not your computer drive.
- The firmware file MUST be named firmware.bin
- All lower case
- Nothing else.
- If your file is named something other than firmware.bin (example: firmware(1).bin) rename it to firmware.bin
- The firmware.bin file must be the ONLY thing on the card.
- Make sure to safely remove the card from your computer to avoid corrupting the MicroSD card.
- Use a FAT Formatted, lower capacity card. We carry 4GB cards pre-formatted as FAT in our store here.
Flashing The Firmware
- To flash completely power off the printer and make sure the LCD and fans are completely off and stopped.
- Copy the firmware.bin file to your FAT or FAT32 formatted SD card. DO NOT put it in a folder.
- Insert the MicroSD card and turn on the machine.
- You will hear a longer than normal (about 10 seconds) power on beep then it will boot.
- If the firmware flashed it will now be named FIRMWARE.CUR on the MicroSD card and you can remove it.
