1. Install uuu.
- Follow [the instruction](https://github.com/NXPmicro/mfgtools#linux) and build `uuu` executable.
- Put `uuu` where the PATH executable points to.
Build and inject U-Boot
-----------------------
1. Run `make udefconfig-sh*` to generate `.config`.
- For Sx1: `make udefconfig-sh1`
- For Sx6: `make udefconfig-sh6`
2. Run `make ubuild` to build whole repository and generate `u-boot.sb`.
- i.MX283 loads a packed U-Boot executable called `u-boot.sb`.
3. To inject the executable into i.MX283 in recovery mode, run `make uuu`.

Build U-Boot
-----------------------
1. Run `make udefconfig` to generate `.config`.
2. Run `make ubuild` to build whole repository and generate `u-boot.bin`.
3. To make `nk.bin`, run `make nkbin`.
- nkbin_maker packs `u-boot.bin` into `nk.bin`.
Build and deploy boot4u
-----------------------
1. Run `make boot4u`
1. Create index.din and copy AppMain.bin
- `mkdir /path/to/your/sd/1st/partition/App/boot4u`
- `touch /path/to/your/sd/1st/partition/App/boot4u/index.din`

Known issues
----------------------------------------
If you using gcc 10 for host compiler, `make ubuild` may fail.
To complete build, open u-boot-brain/scripts/dtc/dtc-lexer.lex.c or u-boot-brain/scripts/dtc/dtc-parser.tab.c then comment out `YYLTYPE yylloc;`
