RE: Very slow kernel/initrd download (RPI + U-boot)
Initially I was using the Pi's built-in firmware to netboot into EDK2. But putting EDK2+iPXE directly on disk makes sense, less flaky and lets you add certs for security.
I've now got iPXE almost booting. It correctly downloads the kernel and initrd at an acceptable speed after pulling your latest commit to the lan78xx driver (thanks!). But iPXE hangs at "EFI stub: Exiting boot services and installing virtual address map...". I've tried messing with the kernel args, adding "net.ifnames=0 dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1" didn't help. It also could be that I'm using a USB drive rather than an SD card. Any suggestions on debugging further? |
