This firmware used to booting up device though usb (sunxi-fel)
This routine used to do things like:
1) Write Uboot Kernel Rootfs into memory and start
2) in kernel, simulate SPI NAND as a usb mass storage device
so you can come to the pc side, use `dd` command to program the flash
- add sunxi-fel binary and script for Windows platform
- add support for MMC device
| routine | version |
|---|---|
| u-boot | v2018.01 |
| kernel | 6.3.7-stable |
| buildroot | v2023.2 |
| Dir | define |
|---|---|
| configs | defconfig for uboot, kernel and buildroot |
| backups | original firmware collected from internet |
| overlays | for buildroot overlay, some scripts and kenrel modules |
if you want develop things based on this project
Get toolchain
wget http://releases.linaro.org/components/toolchain/binaries/7.2-2017.11/arm-linux-gnueabi/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabi.tar.xz
1) downlaod things in version info title
2) use configs i was provided in configs/ dir
i'll give more infomation about this, but not for now.

When you program the flash, you better split the file into servral pieces, like 128MB to 16 x 8MB like this:
# A 8MB window loop
# 1 block = 512 byte
sudo dd if=firmware.bin of=/dev/sda skip=0 count=16384
sudo dd if=firmware.bin of=/dev/sda skip=16384 count=37268
a full dd write may cause OOM problem because the kernel buff/cache feature.
