一早來看到上禮拜五對方願意幫忙看有什麼需要加的
趕緊把目前的 source code 下 mtd driver 的部分 tar 起來給對方
8MB 多
利用 google 雲端硬碟分享 當個備用載點
繼續 trace 吧
參考了 jeffary 給我們的 files
修改了
- drivers/mtd/mtdsplit.c
- drivers/mtd/mtdpart.c
結果還是一樣
趕快寫 mail 讓對方 update 我們這邊的狀況
紀錄一下今天的 trace

其餘都只是 打印罷了
不過今天有試著把 nand_def.h 裡的 CONFIG_BADBLOCK_CHECK 和 MTK_NAND_BMT 打開
build 過了
但跑起來一樣失敗再同一個地方
所以又改回來了
