-1. Overview
|
|
|
- SuperH has an original boot loader. However, source code is dirty, and

|
|
|
- To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu
|
|
|
- started the porting to u-boot in 2007.

- ** README **
|
|
|
- In SuperH, S-record and binary of made u-boot work on the memory.
|
|
|
- When u-boot is written in the flash, it is necessary to change the
|
|
|
- address by using 'objcopy'.
|
|
|
- ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
