XIP, program not starting on LPC54018J4M custom board

ronwal — Thu, 19 Oct 2023 11:38:43 GMT

Hello,

I am currently working on a new custom board using LPC54018J4MET180 with integrated 4MB Flash.

I have been able to run the code when using the "Link application to RAM" setting from MCUXpressoIDE. but it´ll not execute the code with XIP.

When I try to debug from MCUXpresso, the debugger does not get to the main or even ResetISR breakpoint and just says that the thread is running and the following message:

No source available for "(gdb[34].proc[42000].threadGroup[i1],gdb[34].proc[42000].OSthread[1]).thread[1].frame[0]"

These are the debugger log messages:

Hello @ronwal

The "plain load images" control XIP or no-xip, if you want to XIP, disable it (un-check):

About detail, you can refer to <MCUXpresso IDE User Guide > -> plain load image.

Also you can import a xip demo for lpc54018 to test.

Hello Alice

Yes I know it´s setup like this. My problem is, that the program does not load at all when configured for XIP. It hangs before start.

Is there any special configuration I have to make to the internal QSPI flash before able to use it?

My memory config is as follows and I am using the LPC540xx_SPIFI_GENERIC.cfx driver:

Also I checked my linker file if configured correctly:

Image type 3 (XIP with no CRC)
Load_address 0x10000000 (flash)

Also I checked for a possible ISP boot mode

the BOOT_SRC bits9+10 are not set, which means the ISP pins decide
P0.4, P0.5, P0.6 have external pullups and always high, which means Auto boot sequence

My program ist based on the "hello_world_qspi_xip" SDK sample. But I also tried to create i new project from scratch, which shows the same behaviour.

Do you have any other idea I could check?

Thanks

Ron

Hello @ronwal

How about use Flash driver: LPC540xx_SPIFI_SFDP.cfx ?

Hi @Alice_Yang

I tried it, but it gave me the following EXTSPY driver error right away:

ProgramPage (0x10000000, 0x2290, 0x4000) status 0x1 - driver reported driver error - EXTSPI driver rc 112 (0x70)

How can I debug, why the MCU stops in Bootloader ROM area?

From my knowledge there could be many reasons for that, like:

ISP pins
no valid Image found
watchdog timer

But where can I see, what caused the MCU to stop?

Regards

Ronny

Hello @Alice_Yang

Can you please provide some more help because I am really stuck with this problem?

Here I summarize my problem:

Setup:

LPCLPC54018J4MET180,
MCU-Link debug probe,
hello_world XIP sample program

1. Using the LPC540xx_SPIFI_SFDP.cfx driver gives me the following error:

ProgramPage (0x10000000, 0x2290, 0x4000) status 0x1 - driver reported driver error - EXTSPI driver rc 35 (0x23)
15: Target error from Commit Flash write: Ef(49): Flash driver operation gave error.

2. Using the LPC540xx_SPIFI_GENERIC.cfx flashing succeeds with no error.

Even verify the flash with the GUI flash tool afterwards succeeds. After starting the debug session,the program hangs somewhere in BootRom area 0x03xxxxx with message "no debug information avaiable...".

Checking the flash memory with the memory monitor shows all 0x0 at flash adress 0x10000000.

This means to me, that there was nothing written at all and that could be the reason why the program hangs at the bootloader, right?

But why did it say "writting succeeded"?

Any idea?

Thanks

Ron

Hello

After one week of investigating, I found the reason for my problem. Maybe I´ll help somebody...

The XIP image layout was incorrect. The HEADER_OFFSET at 0x28 shall point to the HEADER_MARKER with i typical standard value of 0x160. But in my case I had to change it to 0x158.

After that the image could be loaded.
