M300 - WiFi: warm reboot cause hang 要解在 branch hotfix/v1.76-wifi-eva
昨天已 pull 最新的 branch hotfix/v1.76-wifi-eva
也 build 了 image
mfgtool 燒錄
放到 morris 有特別為了 WiFi 修改的 PCBA 上 - GPIO for IO control power
上電
一直等到 console 亮燈已經是第二次開機的事了(第一次會套用 uboot_env_ver 1.3 並因不知明原因重開機)
在 linux 觀察開機的關鍵 uboot env
bootcmd - 被指定成 run bootcmd_v1.3
root@M301-GW:~# fw_printenv bootcmd
bootcmd=run bootcmd_v1.3
bootcmd_v1.3 - 真正的 bootcmd
root@M301-GW:~# fw_printenv bootcmd_v1.3
bootcmd_v1.3=run turnon_sysled; run reset_ethernet_and_mobile;
run app_choose;
echo run bootargs_${app_primary}; run bootargs_${app_primary};
run nandread_${app_primary};
setenv no_good ${no_good}x;
saveenv;
bootz ${loadaddr} - ${fdt_addr}
check 一下目前開機要注意的點
rc.local
# apply the uboot env variables related to current application
/usr/sbin/icos/uboot_env.sh
# run bootcmd_v1.3 define in uboot_env.sh
fw_setenv bootcmd 'run bootcmd_v1.3'- 每一次都會去把 bootcmd 寫成 'run bootcmd_v1.3'
uboot_env.sh
uboot_env_ver=1.3
if fw_printenv uboot_env_ver | grep $uboot_env_ver
then
echo "uboot_env_ver $uboot_env_ver match, nothing to do"
exit 0
else
echo "uboot_env_ver not match, patching for the current applicaiton"
fi
...
fw_setenv bootcmd_v1.3 'run turnon_sysled; run reset_ethernet_and_mobile; \
run app_choose; \
echo run bootargs_${app_primary}; run bootargs_${app_primary}; \
run nandread_${app_primary}; \
setenv no_good ${no_good}x; \
saveenv; \
bootz ${loadaddr} - ${fdt_addr}'
# set the current uboot env version into uboot env MTD
fw_setenv uboot_env_ver $uboot_env_ver- 如果當前的 uboot_env_ver 不是 1.3 的話就重新把 1.3 的 uboot env 設定全部寫一遍
因為 dual image 的機制
我們無法避免因為 switch partition 的關係
讓上述的 rc.local 再跑一遍把 bootcmd 又改掉
思考一下假設有 10% 的機率發生這件事
10% 裡面應該有 90 % 都是把 把 bootcmd 寫成 'run bootcmd_v1.3' (有更早的 bootcmd_v1.2 和 bootcmd_v1.1)
看一下 bootcmd_v1.3 做了什麼
fw_setenv bootcmd_v1.3 'run turnon_sysled; run reset_ethernet_and_mobile; \
run app_choose; \
echo run bootargs_${app_primary}; run bootargs_${app_primary}; \
run nandread_${app_primary}; \
setenv no_good ${no_good}x; \
saveenv; \
bootz ${loadaddr} - ${fdt_addr}'
就比我預期的重複做了 run turnon_sysled 和 run reset_ethernet_and_mobile
會有什麼壞處嗎...
run turnon_sysled
- 點亮已經被 uboot 點亮的 led
- 完全沒影響
run reset_ethernet_and_mobile
- ethernet 1 和 ethernet 2 被重新 reset
- mobile 被重新 reset
- 就是在 uboot 很短的時間裡 reset 了兩次
看來應該沒什麼副作用
我應該可以完全不去管這件事才對
看來昨天特別把 uboot_env_ver 改成 v1.4 也沒必要了
後續 rc.local 已經不去干預 uboot env 了
mx6ul_14x14_evk.h 的改法應該是這樣

看來是有更新到 uboot
所以對於 firmware_patch.sh 的改動是正確的
試著用這個版本的 mfgtool 作燒錄來測試一下
PASS
看來可以拿給 morris 做測試了
morris 利用 軟體的 restart 測個幾次就發現有一次 IO control power 那跟 GPIO 沒有拉成 low
而且從示波器觀察的結果是從 low 到 high 時
low 的波型至少維持了一秒
uboot 裡控制 IO control power 的 code 如下
int board_init(void)
{
/* Address of boot parameters */
gd->bd->bi_boot_params = PHYS_SDRAM + 0x100;
imx_iomux_v3_setup_multiple_pads(iox_pads, ARRAY_SIZE(iox_pads));

}我看我再修改一下
順便讓 rc.local 在做完的時候順便 reboot
看看會不會卡住

真的發生了
再度修改如下
