Same situation as: Kernel panic - PYNQ Z1
Steps to reproduce:
- Target: PYNQ-Z1 - brand new, host Ubuntu (20.04)
- Download Z1 (V2.7 Image) from http pynq io slash board dot html
(above link is funky, forum only allows 2 links per post :-() - UNZIP using Ubunto UNZIP
- Connect SDCARD to Linux machine
- Use: “dd if=filename.img of=/dev/sdb” -
Did this with multiple SD Cards, including the one that came with the PYNQ-Z1 card - Wait a really really long time … (usb SDCARD is slow!)
- Power Z1 from wall socket (power pack)
- Set jumper to boot from SDCARD
- Power switch off
- Insert SD Card
- MINICOM -b 115200 -D /dev/ttyUSB1
- power switch to ON
- Lights starting to blink
- Linux kernel boots
- MINICOM Kernel Boot sequence and Panic follows:
NOTE: Cannot post full KERNEL boot sequence, when I do - the site says: “Sorry new users can only post 2 links” … and it seems to think I have more then 2 when I include the kernel boot messages
Starting kernel …
