Ok the driver built without the symbol error. Still the same problem with the I2C bus not being idle (0xf8). STOP failed!
Cracked open the tablet just to make sure it is using a GSL chip. It is: 1680E Added this to script.fex [gpio_para] gpio_used = 1 gpio_num = 1 gpio_pin_1 = port:PB03<1><default><default><1> gpio-sunxi loads successfully in /sys/devices/ Thought the rtc was tying up the bus, disabled it in kernel, but still no go. Loaded this driver in linaro, i2cdetect showed that address 0x40 was in use 'UU' and that's good so far. I did notice something about the original android gslx680.ko driver from the 420TPC. It loads multiple firmwares so the fw_extractor tool basically took all of them including the 420TPC which will be invalid firmware data. Contains 14 chip firmwares for the motherboards: 1. GSL1680E_FW_86VS_INET 2. GSL1680E_FW_86VSH_INET 3. GSL1680E_FW_66V_M4302_INET_V2 <--- this is the one for 420TPC 4. GSL3680_FW_shenghexiang0072 5. GSL1680D_FW_86VSH_INET 6. GSL1680D_FW_86VS_INET 7. GSLx680_FW_85V_M501V 8. GSL1680_FW_newdingshengwei_1 9. GSLx680_FW_86FV_M728_TOPSUN_C0801 10. GSLx680_FW_NEWDINGSHENGWEI_OGS_4 11. GSL1680_FW_newdingshengwei_5 12. GSL1680_FW_TOPSUN_OGS_G7009 13.
