I own a J990 without wifi. I am trying to access as many of the GPIOs as is possible.

in running through the echo to direction and echo to value permutitions I ran into several GPIO pins that either do not work as intended or don't work based on the present configuration. I understand that pins 137 though 139 should not work out of the box based on wifi allocation on the board. I have observed odd behavior on gpio168 (i haven't scoped the output, but my dmm just won't settle to a value). pins 140 thru 143 don't seem to respond to commands, although I can cat direction and value, and they seem to take values as intended. same with gpio130 thru gpio135.

maybe I don't understand the hardware manual?

GPIOs that work are:

158
159
161
162
157
156
136
