Hi there,

(breakout  + picozed sdr2 som)

Today when I turned on the PicoZed it didnt boot up. The led status are represented in the following image:

Where there are two green leds on from PicoZed, and red led (usb serial) from breakout, BUT blue led (configuration done) never got lit.
I've managed to force a boot up by manually pressing the blue button (highlighted in violet) from PicoZed board (I guess it's the reset). However It takes quite a lot to boot because it seems it can't get XEMACPS to work and gets stucked there a while:

xemacps e000b000.eth: eth0: no PHY found
xemacps e000b000.eth: XEMACPS mii bus mii_probe fail.
SIOCSIFFLAGS: No such device or address

And when it finally boots up, I can't get eth0 to work either. (To discard SD card corruption I tried with a previous image and the same happens).


Edit: My thoughts -> when booting it's not able to program the PL, so it gets stucked, and when I reboot manually the PS (using the blue button) the PL is not reprogrammed so the kernel can actually boot up, not founding ETH PHY because it hasn't been loaded into PL yet...


Any clue about what may be happening?
