Hi
I am working on a custom board (VPX Based P2020 board) and trying to
port
u-boot-2011.09 (supports P2020 RDB) in it . Our board is similar to
P2020RDB
board and the technical specification is shown below ,
You should always try with the latest version when asking for help
(even if you will eventually need to use an older version for some
other (usually not very good) reason).
->Processor
Freescale QorIQ P2020 processor
Dual PowerPC e500v2 cores at up to 1.2 GHz
512 kB of shared L2 cache
->Memory
1 GB of DDR3-600 SDRAM
128 MB of NOR flash (16-bit)
Through Codewarroier Emulator Tool, We checked the DDR,FLASH,Uart
console
and its working fine without any issue.
when we ported u-boot (u-boot-2011.09) at boot rom location
0xFFF80000, it
fails at invalidate_tlbs in cpu_init_early_f and cannot proceed to
get
serial console .we probed the flash CS while poweron boot , processor
is
keeping bunch of CS( confirms processor able to access flash)
Why its getting held up while invalidating tlb's
Are you sure that's where it's failing? It could be that you just
can't single step through that boot phase. There were recently applied
patches to shrink the "undebuggable" window somewhat.
If that's not it, probably there's no IPROT TLB entry covering the
address you're running out of, or covering the initial RAM area. Have
you tried dumping the TLB?
