Hello,
thanks for your assistance. However, we can't boot freertos at the moment. I
adapted the linker script like this and rebuilt the freertos-demo:
ENTRY(vectors)
SECTIONS {
/* jailhouse arm inmates have to start at address zero */
. = 0x48000000;
.boot : { *(.boot) }
. = ALIGN(4096);
. = . + 0x1000;
stack_top = .;
. = . + 0x1000;
irq_stack_top = .;
bss_start = .;
.bss : {
*(.bss)
*(COMMON)
}
after that i tried to boot freertos in u-boot with the following commands:
=> load mmc 0:1 0x48000000 freertos-demo.bin
reading freertos-demo.bin
198508 bytes read in 45 ms (4.2 MiB/s)
=> go 0x48000000
But the Freertos-demo still doesn't work. Is there anything else we have to do?
Hans, I suppose this build on top of the lib inmate in Jailhouse, ie. its loader
stub, right? That now expects the Jailhouse Comm Region to be present and filled.
Johannes, try commenting out the revision and signature check in
jailhouse/inmates/lib/setup.c for the bare-metal build.
