Ok, so i've increased non-root cell's RAM memory region by 256MB (now it starts from 0x50000000), and changed the reserved memory for hypervisor and non-root cells (on u-boot: mem=1280M, which is equal to 0x50000000 bytes).
It can load the cell, and when it starts it gives me an error related to UART0 (?): [ 62.493128] Created Jailhouse cell "non-root" Cell "non-root" can be loaded Started cell "non-root" Unhandled data read at 0xff000024(4) FATAL: unhandled trap (exception class 0x24) Cell state before exception: pc: ffffff8008480448 lr: ffffff8008473a70 spsr: 80000085 EL1 sp: ffffff800801b9e0 esr: 24 1 1830007 x0: ffffff800d83c038 x1: 0000000000000000 x2: ffffff8008480440 x3: ffffff8008011024 x4: 0000000000000000 x5: 0000000000000064 x6: 0000000000000051 x7: 3030303035323620 x8: 7820612073692029 x9: 2030535079747420 x10: 204f494d4d207461 x11: 3030303066667830 x12: 2071726928203030 x13: 736162202c35203d x14: 3d20647561625f65 x15: ffffffffffffffff x16: 0000000000000001 x17: 0000000000000001 x18: 0000000000000010 x19: ffffffc03a990000 x20: ffffff800d83c038 x21: ffffff800d6104c0 x22: ffffffc03a990100 x23: ffffff800d60e000 x24: 0000000000000000 x25: ffffffc03a99eb00 x26: ffffff8008959a38 x27: ffffffc03a99e600 x28: 0000000000000005 x29: ffffff800801b9e0 Parking CPU 2 (Cell: "non-root") segunda-feira, 5 de Agosto de 2019 às 07:30:59 UTC+1, Jan Kiszka escreveu: > > On 02.08.19 21:46, João Reis wrote: > > I send in attachment the root cell (ultra96.c) and non root cell > > (ultra96-linux-demo2.c) config files, along with the .dtb i am using. > > > > The Image and rootfs.cpio files occupy 89,9MB and 79,4MB, respectively. > (link to > > download them if you want to: > > http://www.mediafire.com/folder/sopta5vdf01yfm8,kwk1yt5jc9zcpl3) > > That's obviously too large for the remaining space in that region.
