Hi All,

I just ordered/received a XB100 gpio board, that I plug into my "old" x115 board.
I'm using latest host tools / firmware from git, and I don't manage to use Leds on xb100 (they are all off)

Code: Select all

bladeRF> version
  bladeRF-cli version:        1.4.0-git-fcd775f
  libbladeRF version:         1.7.2-git-fcd775f
  Firmware version:           2.0.0-git-7d84606
  FPGA version:               0.6.0
bladeRF> xb 100 enable
  Enabling XB-100 GPIO expansion board
  XB-100 GPIO expansion board successfully enabled

At this point all LEDs are off and if I try (by example) what's in Wiki to use RGB LED

Code: Select all

bladeRF> set xb_gpio_dir TLED_RED input
    TLED_RED: input
bladeRF> set xb_gpio_dir TLED_RED output
    TLED_RED: output
bladeRF> set xb_gpio_dir TLED_RED input
    TLED_RED: input

nothing happens

but If if dump all GPIO, and use BTN_J6/J7/J8, I can see changes in value.
So the GPIO board seems ok.

Is there anyone having an idea ? Or the board is DOA ?

Unfortunately, there is a footprint error that was not caught during the last production run for these boards. The MBT3904DW1 parts all have pins 4 and 6 swapped on the footprint in the layout. Feel free to cut the traces or lift the pins and "green wire" to correct the error. We apologize for this oversight and will take steps to correct it.
