ke02z run only in debug

[surajka]

Hello,

I am using processor expert with keil. The problem is that my program runs in debug only. It's not running at por. As I read in the other threads, there is no "librarian" settings found in PE. I am running from internal oscillator. 32khz oscillator is connected but not configured to use. Another problem is that I have to flash the program before debugging(= flashing two times, one when starting debugging and another before that).

Using my own board, opensda that comes with fdrm-ke02z. Fdrm processor is disconnected removing jumper resistor

. Kindly help. Thank you.

Hello Jeremy,

Now the PE project has started to running after flashing, but not after por. The kexx_DRV_lib projects still fail to start on por/after flashing. I think the reset circuitry is clean, I have .1uF cap at the reset pin. Voltage at the reset pin is stable.

Thank you.

Hi Suraj,

I think the root cause is relate to the hardware circuit and you can go for a test again by following the steps below.

1. Just remain the mini-system after remove the stuffs on your own board;

2. Debug and program the KExx_DRV_lib projects to mini-system;

3. Check out the run result of the after programming and POR;

Hope it helps.
Have a great day,

Hello Jeremy,

It worked. Thank you. I had capacitive load on some of the analog inputs(for filtering). Disconnected the inputs and its working fine.

Hi Suraj,

Before answer your question, I'd like to get the more information about the question.

Did the FRDM-KEXX Driver Library package run well on your own board or not?

Did the demo code work well on the FRDM-KE02 board or not?

The kexx_DRV projects as such do not run on my board unless I am debugging(very slow since I have 32khz crystal). They ran well on the freedom board. Similar is the project created by PE. Is my hardware the problem? But it's running smooth in debugging.
