RT1170-EVK program via JLink command line

[yfliu]

Dear support,

I am learning to program the RT11770-EVK device via the on-board debug probe with JLink firmware using command line tool JLinkExe v6.98e

I can connect from JLinkExe commander to the target correctly after issuing the "connect" command and select SWD connection type:

Cortex-M7 identified.

However, I failed to download the target via loadfile command:

J-Link>r
Reset delay: 0 ms
Reset type NORMAL: Resets core & peripherals via SYSRESETREQ & VECTRESET bit.
ResetTarget() start
DISPLAYMIX SRC reset
CM7 SRC reset
ResetTarget() end
AfterResetTarget() start
FlexRAM configuration is restored
syspll2 has been initialized already
syspll2 pfd1 has been initialized already
SDRAM init done
AfterResetTarget() end

J-Link>loadfile maestro_playback.bin
No address passed for .bin file. Assuming address: 0x0
Downloading file [maestro_playback.bin]...
Writing target memory failed.

I guess that the starting address parameter shouldn't be 0, but I can't find the right parameters to use as am I totally new to the RT1170-EVK device.

Please help to share some relevant materials so that I can follow.

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you to use a .srec file instead of .bin file or use the J-Flash to program the image file.

Have a great day,
TIC

Thank you for sharing JFlash tool, however it seems that I can't make it work with on-board debug probe running firmware: J-Link LPCXpresso V2 as the JFlash tool requires a license which I don't have.

Then I tried to program my app using the JLinkExe commander tool, 

J-Link>loadfile iled_blinky_cm7.bin 0x30000000
Downloading file [iled_blinky_cm7.bin]...
...
J-Link: Flash download: Program & Verify speed: 397 KB/s
O.K.

However, after programming, I powered off the device and then power on it, there is no LED blinking. 

Can you please  let me know what should I do?

Hi,
Thanks for your reply.
1) Can you please let me know what should I do?
-- Firstly, you'd better check the bin is good, next, confirm the bin is programmed to chip, as the below figure shows.
By the way, I can program the bin file to the board and it also can boot up well.

Have a great day,
TIC

Here I can see similar thing as your screen shot from JFlash tool, please see blinky-jflash.png attachment.

I did more tests here:

Firstly I tried a "debug" build .elf using gdb/JLinkGDBServer, and I run the program with break points and I can see the GPIO pin write function called correctly from gdb debugger. However, I never see the LED blinking correctly.

Then I tried a "flexspi_nor_debug" build using gdb/JLinkGDBServer, I noticed errors in GDB server side when gdb did "load" operation. However, after resetting these errors are gone. Eventually I got similar experience as the "debug" build. 

I never saw blinky LED even though the app is downloaded to the device with Jlink tools via on-board probe.

Hi，
It seems a bit weird, maybe the issue's related to the board itself, so you'd better check the board at first.
More further, did you ever try to debug the demo as the post shows? if not, please give it a try, especially for the LED blink demo.
Have a great day,

Thanks for the warm followups, it turned out that the board hardware was tweaked thus the default LED light doesn't blink. I tried on another board and it works now.

Sorry for all the trouble.
