CVA6 on VCU118, Trouble Booting Linux, Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

[Darshak Sheladiya]

Hello,

I have generated bit-stream of CVA6 for FPGA prototyping and these are my configuration for cva6:

 

class CVA6VCU118Config extends Config(
new WithFPGAFrequency(50) ++
new WithVCU118Tweaks ++
new chipyard.CVA6Config)

 

In order to avoid the issues with ExtMem, I have set the value of p(ExtMem).get.master.base with 0x8000_0000 and p(ExtMem).get.master.size with 0x4000_0000
as recommended in: https://github.com/ucb-bar/chipyard/issues/954#issuecomment-903528611

 

I am using VCU118 Board for prototyping. However, I am facing problem while booting Linux on CVA6. I am getting this error:
