@ -2554,3 +2554,38 @@ No output, lets enable the PLIC again in the DT. Same.
Probably we have a better chance to fix it in the generic platform.
Let's use a very far away address for the FDT just in case: `0x0_c000_0000`
This one doesn't work:
=> setenv bootargs "root=/dev/ram0 loglevel=7 debug rw earlycon=sbi console=hvc0 ftrace=function ftrace_filter=* tp_printk"
This one yes:
=> setenv bootargs "root=/dev/ram0 loglevel=7 debug rw earlycon=sbi console=hvc0 trace_event=*:* tp_printk trace_buf_size=1M"
=> setenv ramdisk_size 12614846
=> booti ${kernel_addr_r} ${ramdisk_addr_r}:${ramdisk_size} ${fdtcontroladdr}
