0930

試著做完整的 image 燒錄

開起來了... 進了 iCOS 了...

手上這一片 CPU Board 是 14 號

BOOT_CFG1[1:0] - Nand_Row_address_bytes - 該值為 2'b11 - 5 row address bytes

根據 MX30LF1G18AC 的 Table 1. Address Allocation

image

Row address 應該要設定成兩個才對

目前 BOOT_CFG1[1:0] 雖然設定成 5 row address bytes 卻沒影響到開機

BOOT_CFG1[1] 的修改要動到板子上的電阻, 但我可以利用 dip switch 修改 BOOT_CFG1[0]

讓 BOOT_CFG1[1:0] 為 2'b10 - 4 row address bytes

一樣可以開機... 待查

1100

M300 meeting 剛結束

可能是 NAND Flash 開起來了... 氣氛蠻輕鬆的

1435

花時間整理了一下前幾天的日記

  • 復健

在還沒找出問題的癥結點之前

自己真的試了蠻多可能性了

伴隨著一次次的失落

不過如果沒有這些錯誤的嘗試

當 癥結點 出現時, 我也許也無法判斷出那便是問題的癥結點

也多虧了這幾天的嘗試 讓我對 U-Boot 多了一些認識

1450

由於這次的癥結點被發現的關鍵來自 winston 在使用 nand dump 時

看到 OOB field 脫口而出說怎麼都是 bad block

我就來充實一下之試看看什麼是 OOB

1505

看一下 SLC Nand Flash driver

Freescale Yocto Project User's Guide - 6.2 Manufacturing Tool, MFGTool

One way to place an image on a device is to use the MFGTool.
The recipes used to build a manufacturing tool image are linux-imx-mfgtool and u-boot-mfgtool.

為了避免影響到 M300

在 VirtualBox study_ubuntu_16 上做實驗

3.1 Host packages

Essential Yocto Project host packages are:

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath  socat  libsdl1.2-dev

i.MX layers host packages for a Ubuntu 12.04 or 14.04 host setup are:

$ sudo apt-get install libsdl1.2-dev xterm  sed cvs subversion coreutils texi2html docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff curl lzop asciidoc

i.MX layers host packages for a Ubuntu 14.04 host setup only are:

$ sudo apt-get install u-boot-tools

先裝吧

別忘了 make menuconfig 需要 sudo apt-get install libncurses5-dev

3.2 Setting up the repo utility 也照著做

4 Yocto Project Setup 也照做

在 fsl-release-bsp 新增一個 file test_build.sh

MACHINE=imx6ulevk source fsl-setup-release.sh -b test_build

利用 source test_build.sh 來執行

然後 build 6.2 Manufacturing Tool, MFGTool 說的 linux-imx-mfgtool recipe - bitbake linux-imx-mfgtool

jeffrey@jeffrey-VirtualBox:~/fsl-release-bsp/test_build$ bitbake linux-imx-mfgtool

忘了當初建立 VirtualBox study_ubuntu_16 時只有配了 16 GB

1740

再建一個 80 GB 的 VirtualBox ubuntu_16

1750

安裝 samba - sudo apt install samba

Samba 設定 - /etc/samba/smb.conf

...
[jeffbuntu]
path = /home/jeffrey
writable = yes
guest account = root
force user = root
public = yes
force group = root
create mask = 0660
browseable = yes

重新啟動 samba - sudo service smbd restart and sudo service nmbd restart

因為使用 VirtualBox 僅限主機介面卡 的關係

jeffrey@jeffbuntu:~$ ifconfig
...

jeffbuntu 的 ip 是 192.168.56.102

網路芳鄰的功能... 正常

連線網路磁碟機 - Y: - 正常

YOCTO 該裝的裝一裝

先新增 mfgtool_study 目錄後在該目錄下新增 fsl-release-bsp

在 fsl-release-bsp 新增 build_dir.sh

MACHINE=imx6ulevk source fsl-setup-release.sh -b build_dir

利用 source build_dir.sh 來執行

build image 吧 - bitbake linux-mfgtool
