Red Pitaya 122-16: kernel reaches init!
Today I got the NetBSD kernel to start on this Red Pitaya 122-16 using a
device tree derived from zynq-zybo-z7.dts. An important difference that
I only noticed yesterday is that the Zybo Z7 and the 122-16 have their
consoles on different UARTs.
I use the boot.bin that came with the board, btw. I tried the
u-boot-zynq-zybo-z7 boot.bin from pkgsrc, but it didn't appear to start,
possibly owing to that UART discrepancy.
The system gets as far as starting init before it crashes. Here is a
typescript.
