RT1015 Cannot upgrade with NXP-MCUBootUtility

kensu — Fri, 17 Jul 2020 08:27:40 GMT

I am trying NXP-MCUBootUtility tool to upgrade RT1015 EVB,

My step is

1. set the EVB switch(SW8) to download mode.

2. power on EVB

3. Open NXP-MCUBootUtility, MCU Device set to i.NXRT1015, boot Device is FLEXSPI NOR.

4. Port Setup to USB-HID, and Connect to ROM. And It had detect my EVB.

5. Select Application image file to my bin file.(I use the SDK vkmimxrt1015_dev_cdc_vcom_freertos and I use bin file format)

6. Click All-In-One-Action

7. After Process is complete, I switch to normal mode.

8. Reset EVB again, the boot image cannot run.

Does I loss some step or make wrong setting?

Regards

Ken

Hi Ken Su,

Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

Could you please download the MCUbootUtility tool attached firmware:

\NXP-MCUBootUtility-2.3.0\apps\NXP_MIMXRT1015-EVK_Rev.A\led_blinky_0x60002000.srec

Whether this led blinky firmware can works or not?

Please also note, after you download the code, you need to modify the boot mode to internal boot mode instead of the serial download mode.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Kerry

Hi Kerry

Thanks for your comment,

I check the led_blinky_0x60002000.srec, it's no problem.

The demo run OK.

Hi Ken Su,

Check your vkmimxrt1015_dev_cdc_vcom_freertos, whether it contains the SDRAM or not?

If it contains the SDRAM, you need to add the SDRAM DCD cfg in the DCD configuration area.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Hi Kerry

I don't use SDRAM.

I don't modify the memory setting.

And I think RT1015 cannot connect SDRAM.

Any other suggestion?

Should I use srec format file?

If I use bin file, is the base address 0x6000000?

Regards

Ken

Hi Ken Su,

Thanks for your question at first.

Today I have tested it on my side, it's really the interesting things and the test result, and only find in the MCUXpresso IDE, IAR project works perfectly.

I find the main issue is caused by the IVT reset entry point in the MCUBootUtility.

Although it is using the reset handler:

If you use the elftosb tool to generate the sb file, you will find more detail:

imx-flexspinor-normal-unsigned.bd

entryPointAddress = 0x60002000; generate the related file and the sb file, it works.

entryPointAddress = 0x600022A9; generate the related file and the sb file, it is failed

So now, two workaround for you:

1. Use IAR project

1) In the reprocessor options configuration, you need:

XIP_BOOT_HEADER_ENABLE=0

2). entry symbol modified to Reset_Handler

Then you can generate the .srec file, and use the mcubootutility tool, you will download it and works OK.

I also attach my generated the dev_cdc_vcom_fressrtos iar .srec files for your reference

2. MCUXpresso IDE

You can use the \SDK_2.7.0_EVK-MIMXRT1015\middleware\mcu-boot\bin\Tools\elftosb\win

imx-flexspior-normal-unsigned.bd

options {
flags = 0x00;
startAddress = 0x60000000;
ivtOffset = 0x1000;
initialLoadSize = 0x2000;
//DCDFilePath = "dcd.bin";
# Note: This is required if the default entrypoint is not the Reset_Handler
# Please set the entryPointAddress to Reset_Handler address
entryPointAddress = 0x60002000;
}

sources {
elfFile = extern(0);
}

section (0)
{
}

Then generate the .sb file, and use the MFGtool download the code, it also works, I also upload the related files for your reference.

For the detail MCUBootUtility reset handler in the IVT issue, I will check internally, it's really the strange issues.

Any updated information, will let you know.

Kerry
