Hi, Not sure if this right forum to discuss this issue. I have a requirement where I have to update the device tree property with comma-separated values. If I use fdt_setprop() and pass a 2-dimensional array then it is not creating the property with comma separation. Instead I get all the values in same cell separated by space. Is there any other way this should be done? I have referred to some uboot code that used libfdt and does same way as me but even that has the same problem. Any suggestions please? regards, RC
