LS1046ARDB and using CodeWarrior to reflash QSPI flash with original binary files

Daves_Garage — Thu, 09 Jun 2022 16:18:40 GMT

I've manged to erase my QSPI flash (both banks), and would like to restore the original firmware using CodeWarrior/TAP via JTAG on my LS1046ARDB board. Are there instructions for this process, and is there a location to download the file(s)?

Thank you in advance.

Please download and install CodeWarrior for ARMv8 from the following link.

https://drive.google.com/file/d/1Kjq1nLYrtIfWAHYrup5Cf-TTEJI9iWiu/view?usp=sharing

Please download the latest update package from the following link. Then open CodeWarrior IDE, and instill it from Help->Install New Software->Add->Archive.

https://drive.google.com/file/d/1ZHiYWDOhb27o0oD5Brqjn4_vJzRUCKoY/view?usp=sharing

Please save license.dat in Common folder.

Please refer to section "3.2 Working with bareboard application" in C:\Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\Getting_Started_for_CW_ARMv8.pdf to create a bareboard project in CodeWarrior IDE to connect to the target board.

Please enable hard-coded RCW in CodeWarrior initialization file.

In Target Connections panel, please double click LS1046A_RDB(1) to open "Target Initialization File" panel, please modify "USE_SAFE_RCW = False" to "USE_SAFE_RCW = True", then save the configuration and connect to the target board.

Please refer to section "7.7 Using flash programmer from eclipse IDE" in C:\Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\PDF\ARMv8_Targeting_Manual to do flash programming in CodeWarrior IDE.

I uninstalled my current installation of Codewarrior, and downloaded the files you recommended above. After installation of both CodeWarrior and the updates, my system looks like this:

Creating a bare metal project, and compiling, was successful.

Replicating the Target Connection, assigning an IP address, and modifying the Target Initialization file to reflect USE_SAFE_RCW = True was also successful, as shown here:

Pinging the TAP module is successful, as shown here:

Device Manager shows TAP device, as shown here:

Even the CCS utility pings the device, as shown here:

However...

The CCS utility cannot find the TAP module:

Nor can CodeWarrior:

And I still am getting this "Problem Occurred" window.

Also, using a terminal window, and telnet, the communication to the TAP module looks like this:

I have managed to make contact to the TAP device finally by rebuilding the environment on a different system. Still don't know why this matters, but I am happy to make the progress, as this has been plaguing me for several weeks.

I now face a new problem, and was hoping somebody knew how to get past this:

When I attempt to debug the HelloWorld sample project, I get this:

What does this mean, and how do I fix it?

Thanks in advance for any help.

Working with bareboard example, readme file indicates the memory map for target configuration is:

##-------------------------------------------------------------------------------------#
## Memory map and initialization
##-------------------------------------------------------------------------------------#

0x00_0000_0000 .. 0x00_00FF_FFFF 16MB Boot ROM
0x00_0100_0000 .. 0x00_0FFF_FFFF 240MB CCSR
0x00_1000_0000 .. 0x00_101F_FFFF 128KB OCRAM
0x00_2000_0000 .. 0x00_23FF_FFFF 64MB DCSR
0x00_4000_0000 .. 0x00_5FFF_FFFF 512MB QUAD SPI
0x00_8000_0000 .. 0x00_FFFF_FFFF 2048MB DDR

Failure during attempted debug session indicates:

Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x80000d28

Does this mean the debugger is attempting to load the software into DDR memory and execute from there?

Where is the DDR configured within the bareboard example?

Please click "flash programing icon" under "Target Connections" to flash programing directly.

The flash programming algorithm runs in OCRAM.

Probably DDR initialization section provided in CW initialization file is not suitable for your target board.

My target board is the LS1046ARDB, purchased from NXP. - Is the example code not compatible with this board? If not, where can I find the original software image file that can be used to restore the original firmware, and the instructions for flashing it? This was the original question.

Everything done, and all the time wasted chasing the wrong approach to fixing this relatively simple problem is amazing to me...

It's a simple approach of downloading the proper binary image file, and using the flash utility within CodeWarrior to reflash the QSPI NOR memory at the right spot (which happens to be address 0x00000000, so that's pretty simple).

There is a "How To" written already for this effort at: https://community.nxp.com/t5/Layerscape-Knowledge-Base/LS1046ARDB-How-to-update-composite-firmware-image-in-QSPI-NOR/ta-p/1117742

Wish I had been directed to this a few weeks ago... live and learn.
