This article describes the programming eFUSE on VisionSOM-6ULL with VisionCB-6ULL-STD. It requires the UUU tool that may be downloaded from [[Media:Somlabs_visionsom-flasher-efuse.zip|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:
<pre>
uuu.exe vsom_6ull_fuse_sd_boot.lst
</pre>

On Linux:
<pre>
./uuu vsom_6ull_fuse_sd_boot.lst
</pre>

5. Reset the board - if the SD card is inserted, the system will automatically boot.
