burn ,use SD card

[ycsongx]

this is my hardware info:

360 D706 [D816_main]
SOC: T20 WIFI: RTL8189FTV Flash: winbond 16MB Sensor: GC2033

this is my test:

1. burn OpenIPC by SD in u-boot，wifi works, but no driver fot gc2033,and i do not kown how to build myself

mw.b 0x80600000 0xff 0x1000000
fatload mmc 0:1 0x80600000 openipc-t20-ultimate-16mb-2.bin
sf probe 0; sf lock 0;
sf erase 0x0 0x1000000; sf write 0x80600000 0x0 0x1000000
reset

2. i get the thingino code, and try to build a gc2033.ko for T20，i do, but it can't work with openipc
   it seems something wrong with tx-isp-t20.ko and sensor_gc2033_t20.ko [symbloy ot param ]
3. i burn thingino by SD in u-boot, use openipc code [above] , just chage the bin file[ thingino-xiaomi_xiaofang_t20l_jxf22.bin ], it works, but it can't store configs. when i reboot, it will works like a new one, etc: rootpasswd, TZ , hostname, wlanssid, wlanpass......
4. i read wiki and chabge something, it still can't store configs

watchdog 0;
setenv baseaddr 0x82000000;
.........

5. i change a thingino bin, thingino-wyze_c2_jxf22.bin, then, the u-boot seems can't work
   [ i do not think this is a bug , or it because of me, i exec "reset" and "remove the SD card quickly"]

6. i try to boot from SD card use "u-boot-isvp_t20_msc0.bin", cant's work ,it seems like need gpio config.
7. i will try to use CH341 to burn a new binfile

Is anyone willing to give me some advice:

1. why i burn the thingino bin, it cant't store configs
2. how can i build a gc2033.ko work with openipc or thingino

thanks

Hi, we can help you to try and make it work!

To start, you need:

• photos of the PCB for your unit
• bootlog of stock firmware
• dump of firmware (if you have it)

We can make sure the system boots, and then compile a working sensor .ko for your device.

if you can share here, the more information, the better. You can also share in discord or telegram groups. =D
