VIM3 and VIM3L v14

VIM3 and VIM3L start from revision v14 have another DRAM configuration.

Un-bootable images

Some images and OS distros still can use old boot-loaders blobs which not compatible with new hardware revisions v14.

Solution:

rewrite/update boot-loader

Broken boot-loader stuck in loop

This issue happens

After writing old U-Boot into internal eMMC storage for new board rev v14
or latest U-Boot images for SPI-flash

easiest way to fix it just re-flash the device with Amlogic burn tool by suitable eMMC U-Boot image to restore it

https://github.com/khadas/khadas-uboot/releases/download/0.16.4/VIM3.uboot-mainline.emmc.aml.img

restore-vim3-device-uboot.sh

curl -OjkL https://github.com/khadas/khadas-uboot/releases/download/0.16.4/VIM3.uboot-mainline.emmc.aml.img
## reset device into usb-burn-mode
aml-burn-tool -b VIM3 -i VIM3.uboot-mainline.emmc.aml.img
## reboot

Write U-Boot to SPI flash

revision board v12 works
can works for some revision board v14 - some boards have different DDR

Latest suitable SPI-uboot
