ResetISR() before main()

vaclavrojik — Tue, 21 Jan 2020 15:58:00 GMT

Dears,

I have trouble with debugging projects for MK82. I used some of SDK example. Running is immediately stop in ResetISR(), before main(). I tried different examples, I get same results -> ResetISR() before main().

Debugger Console showing:

Program stopped.
0x1c0001ec in ?? ()

Program received signal SIGSTOP, Stopped (signal).
ResetISR () at ../startup/startup_mk82f25615.c:499
499 void ResetISR(void) {

The stop on 0x1c0001ec is the same result on all tested projects.

I use:
LPCLink 2
MCUXpresso 10.3.0
SDK 2.5
MK82FN256VLL15

Where can the problem be?

Thanks

Hi Vaclav Rojik ,

1. Please download the newest SDK for K82.

https://mcuxpresso.nxp.com/en/select

BTW, what's the board you are using? Your own board or the NXP official board?

2. You can use your LPC-LINK2 firmware with JLINK

Then use the JLINK commander, unlock kinetis

Just to do the mass erase at first.

Can you find the ARM core or not?

If yes, then you can use the lastest SDK and try it again.

Wish it helps you!

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

Have a great day,
Kerry

Hi Kerry Zhou
The board is custom. I found and removed short connect between NMI and SWDIO. It was design mistake. Then I maked mass erase by GUI Flash Tool on MCUxpresso. Now is working properly.
Thank You for help.
Vaclav

Hi Vaclav Rojik ，

Thanks for letting me know the details, and that's very good you have found it is the hardware design problems.

If you have any question in the future, please create the new cases, thanks.

Have a great day,
