It fails before FW loading as below. > Maybe you could do some testing with https://github.com/rastersoft/gsl1680 > and > see if you can get it working by skipping the GPIO stuff? > I did a try with Joe's one (https://github.com/jabjoe/sunxi-gslx680) but it is failling with error 1. [ 91.366514] incomplete xfer (0xff) 2. [ 91.366532] reset_chip: gsl_ts_write 1 fail! 3. [ 91.366541] init_chip: reset_chip fail: -70 4. [ 91.366552] gslx680 1-0040: init_chip failed It seems it's due to I2C bus error and someone on LeMaker forum's pointed to me I have probably to switch to 400 khz bus. Another thing I have to do, is to check to which GPIO SHUTDOWN pin is connected ... but for that, I need to tears down my device (no time yet : ski :) ). But if I skip GPIO stuff, how the device will turn on loading phase ? Is writing to the device enough ? -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
