0910

早上 morris 拿了 5 片 m300 麻煩我燒錄程式

這五片的 nand flash 都是空的

需要 mfgtool 來把前幾天準備好的 firmware 燒錄到 m300 的 nand flash 去

目前最新的 firmware - http://192.168.0.242/RD/M300/tags/v1.1

因應未來的需要 - http://192.168.0.242/RD/M300/commit/eb5615697a7e0510d3a6806e531a600c9398e19d

從 core-image-minimal-m300.tar.bz2 改成 rootfs.tar.bz2

因為 FirmwareUpgrade.sh 需要做因應修改的關係...

mfgtool 燒錄上去的 firmware 並沒有修改過的 FirmwareUpgrade.sh... 所以沒有辦法透過 web 來做 v1.1 的 firmware upgrade

直接 git checkout v1.1 自己做出適合 mfgtool 使用的 images... fail

算了... 直接把 m300_v1.1_012C000000129880.tar 解開

把需要的 file 放到 mfgtool 去

修改 ucl2.xml - rootfs.tar.bz2

來幫忙一開始就把 m300 的系統燈點亮

參考 meta-proscend\recipes-kernel\linux\files\m300_ra2_io.patch

再參考 https://github.com/silenceuncrio/diary/wiki/20160727_jeffrey

得知要參考 i.MX 6UltraLite Applications Processor Reference Manual

其中的 26.2 External Signals 的 Table 26-1. GPIO External Signals

sys 這顆燈在該 table 描述如下

Instance Signal Pad Mode
GPIO2 IO20 SD1_DATA2 ALT5

理論上用以下的 uboot command 就能點燈了

  • GPIO2_GDIR - mw 0x020A0004 00100000 1
  • SW_MUX_CTL_PAD_SD1_DATA2 - mw 0x020E01CC 0x00000005 1

寫在 uboot env 裡的 bootcmd

從這樣

=> printenv bootcmd
bootcmd=saveenv;nand read ${loadaddr} ${kernel_b_addr} 0x800000;nand read ${fdt_addr} ${dtb_b_addr} 0x100000;bootz ${loadaddr} - ${fdt_addr}

寫成這樣

=> printenv bootcmd
bootcmd=mw 0x020A0004 00100000 1; mw 0x020E01CC 0x00000005 1; saveenv;nand read ${loadaddr} ${kernel_b_addr} 0x800000;nand read ${fdt_addr} ${dtb_b_addr} 0x100000;bootz ${loadaddr} - ${fdt_addr}

如果 bootdelay 能配合改短就更好了

今天早上沒有會議室可以用

所以 m300 週會挪到下午開 剛剛才開完

針對 Proposal - Dual Images(Code Redundancy) 有個結論

  • 不要只給一次機會沒開起來就做 replace primary 的動作

修改了 proposal

搭配這一版的 uboot env

我們也要修正 FirmwareUpgrade.sh

把原本的

echo "" >> /tmp/FirmwareUpgrade.log
echo "Change uboot env..." >> /tmp/FirmwareUpgrade.log
if df | grep rootfs_a
then
  echo "The active firmware is a, switch to b" >> /tmp/FirmwareUpgrade.log
  echo "Modify uboot env 'bootargs'" >> /tmp/FirmwareUpgrade.log
  fw_setenv bootargs "console=ttymxc0,115200 ubi.mtd=9 root=ubi0:rootfs_b rootfstype=ubifs mtdparts=gpmi-nand:3m(boot),1m(boot_env),10m(kernel_a),2m(dtb_a),96m(rootfs_a),16m(config_a),4m(misc),10m(kernel_b),2m(dtb_b),96m(rootfs_b),-(config_b)"
  echo "Modify uboot env 'bootcmd'" >> /tmp/FirmwareUpgrade.log
  fw_setenv bootcmd "saveenv;nand read \${loadaddr} \${kernel_b_addr} 0x800000;nand read \${fdt_addr} \${dtb_b_addr} 0x100000;bootz \${loadaddr} - \${fdt_addr}"
else
  echo "The active firmware is b, switch to a" >> /tmp/FirmwareUpgrade.log
  echo "Modify uboot env 'bootargs'" >> /tmp/FirmwareUpgrade.log
  fw_setenv bootargs "console=ttymxc0,115200 ubi.mtd=4 root=ubi0:rootfs_a rootfstype=ubifs mtdparts=gpmi-nand:3m(boot),1m(boot_env),10m(kernel_a),2m(dtb_a),96m(rootfs_a),16m(config_a),4m(misc),10m(kernel_b),2m(dtb_b),96m(rootfs_b),-(config_b)"
  echo "Modify uboot env 'bootcmd'" >> /tmp/FirmwareUpgrade.log
  fw_setenv bootcmd "saveenv;nand read \${loadaddr} \${kernel_a_addr} 0x800000;nand read \${fdt_addr} \${dtb_a_addr} 0x100000;bootz \${loadaddr} - \${fdt_addr}"
fi

改成

echo "" >> /tmp/FirmwareUpgrade.log
echo "Replace current primary application" >> /tmp/FirmwareUpgrade.log
fw_setenv no_good .xx

就是讓目前的 primary application 自願集滿兩張 no_good 來讓 u-boot 把它換掉
