[resolved] bad CRC boot loop (again)
-
Got two more Omega2Pro boards yesterday, both refuse to initialise and are stuck in a loop. I made an attempt to recover with a known working firmware (omega2pro-v0.3.1-b211.bin) from USB but the result is the same. It gets to the point when the WiFi driver is loaded. On my one working board it looks like this:
... [ 30.063996] DMA Scheduler Mode=0(LMAC) [ 30.067827] efuse_probe: efuse = 10000012 [ 30.071990] 1. Phy Mode = 14 [ 30.275091] 2. Phy Mode = 14 [ 30.278070] 3. Phy Mode = 14 ...The two new boards only show this:
... [ 33.426104] DMA Scheduler Mode=0(LMAC) [ 33.429936] efuse_probe: efuse = 10000012 [ 33.434141] 1. Phy Mode = 14 ...and then reboot on their own.
Any help would be appreciated. Thanks!

We live and learn. Turns out I didn't provide enough power to the board. Everything's OK now.
