tool chain to build u-boot ver 1.1.2 for Power PC

[lalitchoudhary]

Hi,

Warm greetings!!

We are using u-boot(1.1.2) bootloader for PowerPC board. We are trying to compile bootloader by using montavista tool chain. After done some basic changes it got compile but when it get flashed in board by using BDI it creates some problem. Device is going for reset again and again after displaying below messages:

U-Boot 1.1.2 (CASHEL) (Nov 20 2014 - 20:48:31)

MPC8272 Reset Status: Check Stop, External Soft, External Hard

MPC8272 Clock Configuration

- Bus-to-Core Mult 4x, VCO Div 2, 60x Bus Freq  25-75 , Core Freq 100-300

- dfbrg 0, corecnf 0x1a, busdf 3, cpmdf 1, plldf 0, pllmf 3

- vco_out  400000000, scc_clk  100000000, brg_clk  100000000

- cpu_clk  400000000, cpm_clk  200000000, bus_clk  100000000

- pci_clk   66666666

CPU:   MPC8272 (HiP7 Rev 14, Mask 1.0 0K50M) at 400 MHz

Board: CASHEL MPC8248

DRAM:  128 MB

Later on we have tried ELDK 5.1 tool chain to compile the bootloader, but it get failed and shows -lgcc error, shows below:

Please suggest where we went wrong or some other tool chain which we can use to build the bootlaoder. Thanks in advance.

I recommend using a current version of U-Boot rather than one that is ten years old.  If you got that U-boot code from a third party, you could try asking them for support.  If you insist on using that old version, you should use a toolchain from the same era.  I'm not familiar with MontaVista's toolchains (and you don't say what version in any case), but ELDK 5.1 is from 2011, about 7 years after U-Boot 1.1.2 was released.

Finally, since you say it reboots after the DRAM line, check that your memory configuration (e.g. timings) is correct.

Hi Lalit

I am not sure if it is related but do you have perhaps watchdog

on this board that you didn't tun off ? When you RESET HALT

with your BDI and just sit at the reset vector, is your board

still rebooting ?
