CC2530: Reset to booatloader code in CC2530

Arun Krish

Part Number: CC2530

Hi,

I have an issue after the reset in CC2530. After the powerup of the board, application is starting after one minute but after doing SYS_RESET, directly it is going to the application instead of going to the bootloader. Now I want to fix this issue, so that whenever I am doing Soft_reset it should go to the bootloader first and then to the application.

If the device use boot loader and reset, it must go to boot loader and jump to application. There is no reason the device skips boot loader.

After doing SYS_RESET it should wait for One minute to run the application . But application is starting immediately(may be 2seconds delay) after sending SYS_RESET.

This I have checked multiple times, but application is starting immediately after the reset.

Is there any way to change the bootloader time for example, making it as two minutes instead of one minute.

I suggest you to add LED blinking in boot loader to verify this.

In my custom board I don't have any LED for indication..

You can use a GPO to do it and check with scope.

Are you sure you merge boot loader and application correctly?

Yes I merged the code. After doing the programming , Application is starting after one minute, this I have tested.
But whenever I am giving SYS_RESET , application is starting immediately.

I can share the video also if you want....
