Not able to flash/debug S32k144 evb

[ShivarajBavache]

Hello ,

I am working on S32K144 board, with S32DS IDE, when i tried to flash, I got this error and reset led (D1) is continuously on.

Even "Emergency kinetics Device recover by full chip erase" option also didn't work.

 I'm able to detect the board on my computer. but I am not able to flash/ debug .

Can someone help me with this, please?

Hi,

if the reset is asserted all the time (it would be nice to double check this by an oscilloscope to see if reset is toggling after power on or not), I can see only two reasons:

- it's some HW issue (damaged board or micrcontroller)

- did anyone played with strict secure boot mode on this device? If the strict secure boot mode fails, the device will never leave reset and it's not recoverable.

Regards,

Lukas

Hello Lukas,

I am getting reset only during flashing. Once i click on debug, D1Led(reset led) turns on.

The debugger resets the device before programming, so you should see the LED is turned on for short period of time. If it is asserted all the time, it's not expected behavior and I can't see reason for that. Do you need to power off / power on the board to deassert the reset?

Was it working before that? What was the last operation?

Regards,

Lukas
