mboehmer Posted October 5, 2020 Posted October 5, 2020 HI all, first of all, I found thi sissue adopting a new board to the CSC tree, done by @balbes150. As it seems to be a problem of RK3288 in general, I post here, in case please move the topic to the approriate place. I have a JLD076 board, and started adjusting the DTS to the schematic. According to the schematic, and the TRM of RK3289, there is a maximum number of 160 GPIOs. This is also the number I get from my schematics. So I expected th get suitable number of pins from gpioinfo (bank:number 0:19, 1:4, 2:18, 3:28, 4:26, 5:12, 6:19, 7:24, 8:10). Instead, I get listed (0:24, 1...7:32, 8:16). I tried now to set ngpios for the &gpioX entries in the DTS, both in the rk3288.dtsi and the rk3288-ev-act8846.dts, and verified by dtc that the ngpios entry is in the DTB file, but gpioinfo still shows the wrong number of pins. This seems to be hardcoded somewhere... any ideas on what I do wrong here? Best regards, any help is appreciated. Michael
