LS1088A-RDB PB - CodeWarrior CWTAP JTAG CPU Connection

rapter465 — Tue, 08 Nov 2022 14:04:35 GMT

I am currently trying to connect to the CPU on the LS1088A-RDB (PB) via JTAG on a CWTAP device. The goal here is to try to flash NOR from the JTAG to prove out recovery capabilities. In trying to connect, following the CodeWarrior Guide "CWARMv8TM - CodeWarrior Dev Studio for ARMv8", I am getting the following error:

(gdb) source ../../gdb_extensions/flash/cwflash.py

Initialized board LS1088A_RDB.
Flash programming operation failed.
//
Additional error details:

I do recall that I had to patch LSDK 21.08 ddr_init.c for this dev board to get it to startup. I figure that I need to modify the LS1088A_RDB_init.py, but have no idea what value I should be updating it with. Any help would be greatly appreciated.

First please download and install the latest CodeWarrior for ARMv8 11.5.11 update package.

Please login "www.nxp.com", then download CodeWarrior for ARMv8 11.5.11 update package from "MY NXP Account->Software Licensing and Support->View accounts->NXP Software->CodeWarrior Networked Suite - Specialist Level->11.5.X CodeWarrior for QorIQ LS Series ARMv8 ISA -> CodeWarrior for ARMv8 v11.5.11 b220924 Windows Offline Update".

Then open CodeWarrior IDE and install CodeWarrior 11.5.11 update package from Help->Install New Software->Add->Archive.

If the above doesn't work you need to modify LS1088A_RDB_init.py manually.

Please boot up the target board to stop at u-boot prompt.

In CodeWarrior IDE, please create a QCVS DDR project from File->New->QorIQ Configuration Project, in DDR configuration panel, please select "Configuration mode" as "From target", then click "Read from target".

After creating the project, please refer to file ddrCtrl_1.py under Generated_Code folder in Project Explorer panel.

Thanks - I was able to get past DDR initialization after I manually merged the output of ddrCtrl_1.py into cwflash.py. Now that I am past that error, I am running into another:

I validate that I am booting from QSPI NOR, and paused u-boot at startup. Additionally, I verified on the LS1088A-RDB (PB) that the CWTAP_SEL jumper is removed to ensure it's in ARM program mode (as opposed to CPLD).

Have you modified FLASH_TYPE = "qspi" in C:\Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\gdb_extensions\flash\cwflash.py?

You could do flash programing in CodeWarrior IDE.

In Target Connections panel of CodeWarrior IDE, please duplicate LS1088A_RDB to generate LS1088A_RDB(1), then click the flash programmer icon to do flash programing.
