That's the first thing I did after telnetting to stock firmware. Attached a mass storage device (usb flash) and made a full backup. I think that's what every reasonable person would do. > >>> The image for MPR-A1 works nicely on this board so there's no sense > >>> adding it separately. > >> > >> What about the GPIOs? > > > > Tested LEDs and the button, work as expected.

I confirm his results for GPIO8. However, he's certainly using some custom firmware without telling anybody because rt5350.dtsi has "disabled" for the second "bank" of GPIOs, so I can't test anything higher than 23. But also the existing MPR A1 dts doesn't switch SW_PHY_LED to GPIO, so I can't test GPIO 22 and 23 either (unless I recompile which will happen only later). I wished he shared the improvements with the community... Among all the lower GPIOs I wasn't able to find anything apart from GPIO8 (and known leds and the key of course); neither usb power / root hub controls, nor JTAG pins, nor the others :/ Here's a dirty script I'm using to probe for gpios, bisecting is fast enough (giving first and last gpio numbers as arguments): #!/bin/sh cd /sys/class/gpio for i in `seq $1 $2`; do echo $i > export; echo out >gpio$i/direction done nums=`seq $1 $2` while true; do for i in $nums; do echo 0 > gpio$i/value done for i in $nums; do echo 1 > gpio$i/value done done -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercer...@gmail.com _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
