Hello Segger-Support,

I have trouble with J-Link used from "IAR Workbench IDE". If i download my
program, so i get "J_link Dialog" with "Failed to get CPU status after 4
retries. Retry?" after this i can only abort the current session (see appended log output).
The same failure is occured with "Debug iFlash" configuration is in use.

When i put the board into "boot mode" via J3P1 (MODE0), J3P2(MODE1) only the download to
RAM is successful (Debug iRAM configuration), download to flash is therefore failed.

I use TMPM350-SK (IAR KickStart Kit) evaluation board.


* Here is the Debug Log from IAR Workbench IDE:

Have you any hints?

Thanks in advance for your support.

Hi Alex,

> As a first try, you should check if basic communication with the device using J-Link is still working.
> The simplest way would be to download the latest version of the J-Link software and documentation package (V4.40b, segger.com/jlink-software.html)
> and start the J-Link Commander.

> Is J-Link still able to connect to the device?
Yes

> Is J-Link able to halt the CPU using the "h" command?
It seems so.

> Could you please post the output of J-Link Commander?
Sure.

Greetings Eduard

Hi Alex,

i send you the log file from last fail.
It seems, that mcu could not been halted.

> T0940 002:296 JLINK_IsHalted() returns ERROR (0011ms, 2291ms total)

Thanks,

Eduard

Hi Alex,

i played a "little bit" with Reset Option (J-Link/J-Trace; Setup Tab).
After switching Reset to "Connect during reset" the failure is gone.
See following log:

Hi Alex,

> Is it possible that your development project is configured to use JTAG
> while the working project is configured to use SWD and your device is only connected via SWD?

No, it doesn't.

> From the log files it looks like this...

Hm..
