NOR FLASH boot for M7 FAIL

ofer-bahar-guardknox — Thu, 06 Jul 2023 15:48:48 GMT

Hello

I'm unable to boot from M7, Target is GoldBox RDGB2, application M7 single core works in debug, flashed OK to the QSPI NOR flash, but does not being boot !

Steps I do

1. Building and checking a M7 application from the examples Siul2_Port_ToggleLed_S32G274A_M7

2. Did all steps from: HOWTO: Use IVT Tool To Create A Blob Image S32G274... - NXP Community

3. for the DCD i imported the one from the project, only exported it as binary

4. for the application bootloader RAM entry pointer I put the intc_vector

5. for the application bootloader RAM start pointer I put the int_sram from the linker file

6. I tried either with or without QuadSpi parameters file e.g. mx25_sim200ddr.bin, or mx25_sim133sdr.bin

7. export a blob, looks OK

8. flash the target, it completed OK

9. set the switched to boot from NOR flash, make power off, power on

Result : Nothing!, the LED should have been blinking

what am I missing ?

thanks

Hi,

On the 8th step, we are seeing that you are selecting the "ivt_blob_image", which is the default option provided, not the blob you have created.

Where are you saving the blob image? You should point to the blob image you have created.

Please, let us know.

Hi Daniel

I saw that as well and of-coarse tried the blob image I created, but => the same result

maybe it's the DCD? is there a ready & good DCD binary, suitable for the RDB2, that I can download or you can send me ?

what else can be the reason ?

Hi,

We create our IVT without the need of the DCD following the Software Enablement Guide, we modify the linker as shown in the guide and just select the QSPI interface instead of the SD card. We are not seeing any issues on this regard. You can access this guide under the RDB2 product page (link: S32G2 Vehicle Networking Reference Design | NXP Semiconductors)

As for a pre-built DCD, there should be one provided under the HSE DEMOAPP or the integration reference examples, if needed.

Please, let us know.

I will try the same procedure as in the software enablement guide as well, through its for SD card, hope it works, and if so i will configure to NOR QSPI FLASH and let you know how it works

Look like the RAM entry pointer is different between few documents

Trying the one in the enablement doc works
