I have tried exporting and doing echo for gpio 250,248,237,238 and 234 in x27 port.
But when i tried the same for gpio108,109 and 233 of same x27 port, it shows “echo : write error : Device or resource busy”
Also how to find linux gpio numbers of x14 port?? i compared the ixora datasheet and apalis datasheet to find linux gpio numbering.Out of that only gpio224 worked.
whats the reason behind these errors?
