`MIMRT1050 + mbed` uploading and debuging with J-link

[EthanGuo1995]

In my limited experience with PlatformIO IDE, I have been searching for a long time on network but nothing useful.
So I wonder if I can get some help here about how would I modify configuration in file platformio.ini to upload and debug my project with J-link.

My platformio.ini shows as follows:

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:mimxrt1050_evk]
platform = nxpimxrt
board = mimxrt1050_evk
board_build.mcu = MIMXRT1052DVL6A
board_build.upload.offset_address = 0x60000000
framework = mbed
debug_tool    = jlink
upload_protocol = jlink

MCU: MIMXRT1052
platform: nxpimxrt
board: MIMXRT1050-EVK
framework: framework-mbed 6.60200.200722 (6.2.0)
IDE: PlatformIO IDE (VSCode)

Thanks in advance.

Hi @EthanGuo1995 ! A few comments:

• Looks like you incorrectly specified the offset address, it should be board_upload.offset_address = 0x60000000.
• If you're overriding the MCU and using JLink as the debug tool, then it might be a good idea to override the JLink device as well board_debug.jlink_device = MIMXRT1052DVL6A

Everything else looks fine.

Thanks you!!! It can work.

And How would I debug the target. Is that correct showing as follows:

......

; Debug options
; debug_tool    = jlink
debug_tool = custom
debug_server =
    JLinkGDBServer
    -singlerun
    -if
    SWD
    -select
    USB
    -port
    2331
    -device
    MIMXRT1052DVL6A

Why do you need a custom debug server? It should work with debug_tool = jlink.

Emmm. I have changed it back now. But it still didnot work, showing message on console like this:

In Keil, it seems to use evkbimxrt1050_flexspi_nor.ini as initialization file for debuging:

Does it also need here? And if so, how would I add it?

There might be a plenty of reasons. What project are you trying to debug? Does it work if you only upload it to your board? I see that JLink still uses MIMXRT1052DVL6B as the device. Is there any chance that active hardware watchdog is resetting the target before finishing programming?
