緊急 task
M360P - Avoid partition is empty from production line
先 build 一版最新的 M360P[release/v1.05]
雖然我應該在 uboot 解決這件事
但如果在下禮拜三之前來的及的話
12 GRE 這個 task 要作在以下兩個 generic 的 profile 上面
- 1_APN2
- 3_WIFI
1305
先盤一下 M360P 目前的開機訊息
我可以很大程度的利用 console 來 output 我需要的信息
因為 M360P 成品是不提供 console 的
也就是說目前 console 的 output 使用者完全看不到

在 System Boot system code via Flash at dual image a. 的情況下
利用 linux shell - mtd erase reserve 把 partition b 區清掉
再利用 fw_setenv no_good .xx 讓下次開機從 partition b 開機
會發現 console 停在以下的地方

我可以利用這一點來抓出 partition a 和 partition b 是否為 empty
另外還可以參考 uboot-m360\lib_mips\board.c - int copy_image(int dir, unsigned long image_size)

目前已經實作出一份堪用的 uboot
明天再多做幾次測試後再 commit
記得整理一下 wiki 禮拜五可以分享
