Other Parts Discussed in Thread: CC2531EMK

Hello,

I am working with cc2531EMK device and ZNP example ( stack 2.3.1).

In the example project I can obtain the ".hex" file to program the bootloader and without erasing  necesary memory for this.

I have used this ".hex" file and  the bootloader starts when the USB is plugged . I don't want it, I would prefer control the moment to start the bootloader.

Is this possible? if it si possible, how can i do it?

My idea is to implement a new command in ZNP comunication and when the new command arrive start the reprogramation.

Regards

    I have tried changing something in code, but without good results.

    The changes:

    - Delay time in boot : uint32 dlyCnt = 0x100; //0x260000 

    - I have inserted Boot files in ZNP project (sb_exec.c, sb_exec.h, sb_main.c and sb_main.h) with their paths. 

    I try to build the project but this mistake appear: Error[Pa037]: function type not callable , usbirqHandler();

    I don't understand the reason, can somebody help me?
