p2020 RDB REV register setting to use ICE

[yehudamarko]

can you provide with registers setting for ICE / code warrior for the following board , P2020RDB REV C .

I have difficulties to set the DDR regs

[yehudamarko]

Yes, on bottom side of PCB there is a sticker with only one line: SCH-21802 REV D.

[ufedor]

The SCH-24802 has DDR2 SDRAM, so it is needed to use P10xx-P20xxRDB_P2020_init_core.tcl

[ufedor]

On the PCB there should be a sticker containing two lines one of which is "SCH-nnnnn REV x".

Please provide information from this sticker.

[yehudamarko]

did you attach any file of the regs setup, ?

I don't see any file attached

[ufedor]

No.

> but uboot is running from DDR , so ddr is working.

U-Boot is running from the L2 SRAM.

CCSR base address is 0xFFE00000

[yehudamarko]

I see now --- no prompt.

but uboot is running from DDR , so ddr is working.

can you provide the CCSBAR adrs defined while uboot is running.

U-Boot is running from the L2 SRAM.

CCSR base address is 0xFFE00000

P2020RDB-PA REV G (u-boot prints RevC)

CPU 1000 MHz

DDR 667 MHz

CPU REV 1.0

TDA3474

This is the output from u-boot – it does not continue past last line, i.e. no prompt:

----------------

How do I get the DDR registers? How do I derive the address where they are mapped?

Thank you

[ufedor]

In this case it could be assumed that the DDR SDRAM is damaged.

Please use a debugger to check the DDR controller registers settings in the problem state.

[ufedor]

Please note that if the board is bootable, than it is possible to ptint the DDR controller registers by the 'md' U-Boot command:
