Programming eFUSE bits on VisionSOM-6ULL
| NOTE! The described operation may be performed only once and cannot be reversed! |
This article describes the programming eFUSE on VisionSOM-6ULL with VisionCB-6ULL-STD. It requires the UUU tool that may be downloaded from here.
1. Enable the eFUSE boot mode by setting the BOOT[1:0] signals to 00.
2. Connect the VisionCB-6ULL-STD board to the PC using the USB-OTG connector.
3. Power-on the board - the processor will starts in the serial downloader mode because the eFUSEs are not yet programmed.
4. Run the downloaded UUU tool:
On Windows:
uuu.exe vsom_6ull_fuse_sd_boot.lst
On Linux:
./uuu vsom_6ull_fuse_sd_boot.lst
5. Reset the board - if the SD card is inserted, the system will automatically boot.
