昨天修打檔車的結果

• 猜測 - 後輪的齒盤該換了 - 猜錯了
• 暉達機車行 - 新竹市東區光復路二段20號 - 真的很不錯
• 鍊條調緊一點就解決了我多日的困擾
• 順便換了前輪的輪胎 - 1500

試著把最新的 code 利用 mfgtool 燒錄到 nand flash 去

參考 - https://github.com/silenceuncrio/diary/wiki/20160713_jeffrey

燒錄的過程是沒問題

不過要把 linux 從 nand flash 開起來的話

[zImage-imx6ul-14x14-evk-gpmi-weim.dtb] 需要有 nand flash 的相關資訊

如果我直接使用 How-To use NAND boot on i.MX6UL EVK board 上的 dtb

因為少了 m300 的硬體描述 一開始的 [rc.local] 就會失敗了

...
Running local boot scripts (/etc/rc.local)ifconfig: SIOCSIFFLAGS: No such device
error

Freescale i.MX Release Distro 3.14.52-1.1.1 imx6ulevk /dev/ttymxc0

imx6ulevk login:

得想辦法跟我們目前的 dtb 作整合

1730

我們目前的 dtb 整合 nand flash 的結果如下

是利用 上 patch 的方式

這個 patch 目前如果 commit 到 svn 會讓 sdcard 功能異常
