LED blinky example from SDK of RT118X can't startup after power on

shengs — Wed, 24 Jul 2024 06:54:44 GMT

I have a MIMXRT1180-EVK board, and my IDE is MCUXpresso for VS Code, the SDK version is 2.16.000, J-Link is used, JP4 is shorted. I have questions about debugging.

First, SW5[2:4]=001, the "evkmimxrt1180_rled_blinky_demo_cm33" work well using the "debug" build configuration, I can download and debug the demo code, and the "D6" LED was blinking. But it can't work after power on again.

Second, SW5[2:4]=100, I can download the blinky demo using "flexspi_nor_hyperram_debug", but can't debug it. The breakpoint in the main() can't be reached. I don't know why.

Third, I open the "vkmimxrt1180_rled_blinky_demo_cm33\armgcc\flexspi_nor_hyperram_debug\rled_blinky_demo_cm33.elf", find that it is start from 0x28000B00. And the "vkmimxrt1180_rled_blinky_demo_cm33\armgcc\MIMXRT1189xxxxx_cm33_flexspi_nor_hyperram.ld" show that the app_image_offset is 0x0000B0000.

Why does the image not start from 0x28000000?

Fourth, after power on again, I readout entire flash using J-Link, and I find that the content start from 0x2800B000 is same with rled_blinky_demo_cm33.elf. And the content between 0x28000000 and 0x2800B000 is 0xFF.

Can you help me? I want the code startup after power on again.

Sorry for mistakes.

0x28000B00 should be corrected to 0x28000B000, 0x0000B0000 should be corrected to 0x0000B000.

Hi @shengs

I tested it on my RT1180EVK Board. It can work.

But i use the MCUXpresso IDE.

The SW5[2:4]=001, and i debug the evkmimxrt1180_rled_blinky_demo_cm33. when i reset the board, it can work.

You can try to download MCUXpresso IDE.

I will also try to use VScode.

Hope this will help you.

Hi, @Harry_Zhang

I tested blink demo using MCUXpresso IDE before, both debug and release mode. It works well. But my team tends to use VS Code as our IDE for some reasons.

SW5[2:4]=100. The LED blinks @1Hz after power on again.

Hi @shengs

Can it work now?

No yet with VS code.

Have you tested it?

Harry_Zhang — Fri, 26 Jul 2024 08:47:56 GMT

Hi @shengs

I have tested it.

As you mentioned.

I imported the evkmimxrt1180_rled_blinky_demo_cm33,

and set flexspi_nor_debug as default.

I didn't change the SW5.

It can work.

Hope this will help you.

Can you debug it? Can it blink power on again?

Hi @shengs

Sure, I can debug it, and it can blink power on again.

I notice that the on-board debugger is used in your setup. But I use J-Link.

shengs — Fri, 26 Jul 2024 09:10:48 GMT

Can you use J-Link to test again?

The JP4 and JP5 is shorted on my board.

Hi @shengs

Are you configuring flexspi_nor_debug as the default mode?

I tested it with jlink, but it can debug only in debug mode.

I flexspi_nor_debug mode, it can not work.

是的，我使用Jlink的情况下只能在“debug”或者“release”模式下调试，其他所有模式都不行。你这边也是这样吗？我最终目的是想在flexspi_nor和flexspi_nor_hyprram模式下使用Jlink能正常调试，且板子重新上电后点灯程序能正常启动。

是的，如果使用jlink，目前Vscode中只能在“debug”或者“release”模式下调试。如果您想板子重新上电后点灯程序能正常启动。建议用板载debuger。

如果使用J-Link，如何才能使用其他带flexspi的模式调试、重新上电运行？之前说过，我们的项目组期望真实产品的开发过程使用J-Link。谢谢！

Hi @shengs

如果您想用jlink 结合flexspi_nor_debug，经过测试，IAR 没有问题，但是vscode目前存在问题，目前正在调查这个问题。

谢谢

原因找到了，是XIP_BOOT_HEADER_ENABLE没有使能，见"MCUXpresso_SDK_V2.16_MIMXRT1180-EVK_Repository\docs\Getting Started with MCUXpresso SDK for MIMXRT1180-EVK.pdf"

对于MCUXpresso for VS Code，在evkmimxrt1180_rled_blinky_demo_cm33\armgcc\flags.cmake文件里更改。

shengs — Tue, 06 Aug 2024 00:24:57 GMT

对于MCUXpresso for VS Code，使能XIP_BOOT_HEADER_ENABLE可以使flexspi_nor_模式的代码上电启动，但是仍然不能调试。
