LS1046ARDB Bringup Scan Timeout

Rinke — Mon, 18 Nov 2024 21:02:10 GMT

Hi,

In preparation for our own custom board I am trying to bring up our LS1046ARDB devkit board. Its the default NXP devkit with accompanying DDR RAM. I am following AN12270 and have made changes to the LSBP.tcl, grabbed the DDR timing values using the QCVS tooling. Moved over the values from ddrCTRL_1.py into the ddr-init file and ive tried running the lsbp.tcl file. I have added some extra debug statements but it seems during the writing of u-boot the DDR RAM no longer responds?

RCW: 0x9F

See files attached

I dont really understand what I am missing. Any help or pointers are really appreciated!

Yes the lsbp is pointing to a different named ddr-init file. But thats not the issue

Please confirm you have done the DDR validation with the QCVS DDR on the customer board with correct DDR clock.

QCVS_DDR_User_Guide

And please confirm the parameters could pass the "Diagnose connection"

In fact, if you could connect the CodeWarrior TAP, you could program the flash follow the C:\Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\PDF\ARMv8_Targeting_Manual
