From Wiki-DB
Introduction
This guide is about how to flash the AV96 board via universal mass storage.
Start UMS mode in U-Boot and flash the image
- Set Avenger96 boot mode to SPI boot.
- Start the board and stop in U-Boot by pressing any key.
- Connect USB cable between USB OTG and PC host port and call the following from U-Boot command line.
ums 0 mmc 1
-> Mass storage is detected from the Host PC.
- Now you can use balena etcher to flash the dh-image-demo to eMMC.
Update U-Boot from USB stick
After the image update you will have the problem, that the originally flashed U-Boot is not capable to load the new Image. To fix this you have to update the U-Boot on the SPI flash:
- Copy the U-Boot and SPL binaiers to a USB stick and plugin the flash drive at the AVenger96 Host port
- Start U-Boot and set the following ENV variable:
env set update_sf 'usb start && env set loadaddr 0xc2000000 && env set loadaddr1 0xd2000000 && load usb 0 ${loadaddr1} u-boot-spl.stm32 && env set filesize1 ${filesize} && load usb 0 ${loadaddr} u-boot.itb && sf probe && sf erase 0 0x200000 && sf update ${loadaddr1} 0 ${filesize1} && sf update ${loadaddr1} 0x40000 ${filesize1} && sf update ${loadaddr} 0x80000 ${filesize} && env set filesize1 && env set loadaddr1'
- Run the script
run update_sf
- Restart the board -> New U-Boot will start up and will load the flashed dh-image-demo
