I'm trying to reset by software.

void (*reset)(void);

reset = (void(*)())0x200000;

reset();

It is not working.

Can you explain why it doesn't work?

Thanks.

Hi,

I didn't get the question. Why did you use 0x200000?

Please let me know what is the user scenario to do the reset?

Thanks,

After remove device, my board can't work to re-pairing and connect.

I need to reset my board.

At first time, I tried to jump to address 0x0. But it didn't work.

And I find follows document about cyw20719(I can't find 20721's memory layout). The link is https://community.infineon.com/t5/Resource-Library/CYW20719-Memory-Layout/ta-p/246353.

Despite that it is 20719, I re-try to reset with ram start address.

Thanks your interest.

Hi,

You do not have to reset the device in this way. If you are attempting for repairing, and the peer device is a new device, 20721 stack should allow it  undergo the whole pairing process. Soft or hard reset is not a recommended if the device does not allowing for re-pair. 

Could you please share me the IDE, SDK versions and the application which you use? Is it a custom app?

Thanks,

I' sorry I'm so late.

I use eclipse included in modustoolbox 2.4, wiced_btsdk 2.6, Audio_Headset_and_Speaker.

Thanks for your efforts.

I would suggest to use the latest SDK. BTSDK3.2.

Your SDK (2.6) is pretty old and not compatible with Modustoolbox2.4.
