I have already used AT!USBCOMP for disable the DM port(I didn’t see the message “It can be
disabled on WP76xx/WP77xx, but cannot be re-enabled.” at that moment).
I trid to use AT!BOOTHOLD for disable the DM port for a short time(before next power on),and used swiflash to flash the spk file to my device.
But when I done this, and power on my device, the DM port is still disable.
Does anyone know how can I keep my device’s DM port enable for all time?
Sorry for my poor English.
