How to flash images using "NOR flash" * [ ] make sd card 2 partitions (boot, root) * [ ] download pre compile images & copy images to sdcard * [ ] use below commands to flash images from sdcard to NOR flash {% tabs %} {% tab title="make sdcard partition" %} #### 1. SDCARD Partition Reference [video](https://www.youtube.com/watch?v=_dQQEVeSrgo) #### 2. Click here to Download images and copy images to sdcard ``` $ cd RBNR-20.0.0 $ cp boot.bin qspi_boot.bin $ cp u-boot.bin qspi_u-boot.bin $ cp qspi_boot.bin qspi_u-boot.bin /media/$USER/boot $ sync $ umount /media/$USER/boot ``` #### 3. Flashing on Board {% endtab %} {% tab title="on board flash to NOR" %} connect sdcard to board -> Open **minicom** -> prese Reset button -> Press any KEY to stop boot at bootloader. ``` # boot.bin flash to NOR sf probe fatload mmc 1 0x22000000 qboot.bin sf erase 0x0 0x10000 sf write 0x22000000 0x0 0x10000 # u-boot.bin flash to NOR sf probe fatload mmc 1 0x21FF0000 qu-boot.bin sf erase 0x20000 0x80000 sf write 0x21FF0000 0x20000 0x80000 ``` Now **Remove the sdcard** from the Rugged Board A5d2x sdcard slot and reset the board.
