花了一些時間跟 meteor 相處

文件的品質真的很不錯

build 出 SD Card 用的 image 但 U-Boot 要有 nand 這個 command 可以使用

燒錄完的 image dd 到 sd card 後開機訊息如下

發現自己沒套用 How-To use NAND boot on i.MX6UL EVK board 的 mx6ul_14x14_evk.h

參考 - https://github.com/silenceuncrio/diary/wiki/20160712_jeffrey

先用克難的方式來套 mx6ul_14x14_evk.h

• bitbake u-boot-imx -c clean
• bitbake u-boot-imx -c unpack
• 套 mx6ul_14x14_evk.h
• bitbake u-boot-imx -c compile

build SD Card 用的 image

將 image dd 到 sd card

U-Boot 2015.04-imx_v2015.04_3.14.52_1.1.0_ga+g6cf684a (Dec 06 2016 - 06:28:01)

目前手上這片 CPU board 是 NAND: 256 MiB 的 1 號

換成舊的 NAND: 128 MiB 也一樣

參考 [i.MX Linux User's Guide] - 4.3.4 Copy a bootloader image

還是有問題

1530

參考 - https://github.com/silenceuncrio/diary/wiki/20160721_jeffrey

感覺又卡在之前不了解的地方了

1600

套 mx6ul_14x14_evk.h 的方式有誤

重新整理如下

• bitbake u-boot-imx -c clean
• bitbake u-boot-imx -c unpack
• 套 mx6ul_14x14_evk.h
• bitbake u-boot-imx -c compile
• bitbake u-boot-imx -c deploy
• 參考 [i.MX Linux User's Guide] - 4.3.4 Copy a bootloader image

使用 D:\m300\tools\L4.1.15_1.0.0_ga-mfg-tools\L4.1.15-1.0.0_ga-mfg-tools\mfgtools

來對新打回來 NAND: 256 MiB 的 m300 CPU board 做燒錄的動作

已確定可以正常地從 nand flash 開機
