Hi,

I'm facing a problem while developing the firmware for a 100W power adapter.

I programmed the CYPD3196 via SWD and J-Link. Afterwards I could not program it a second time. In openocd I get the error "DP: cannot read IDR".

I suppose I have chosen the wrong bootloader. Because I was not able to find the bootloader for the CYPD3196, I utilzed the one for CYPD3175. Is it possible that this is interrelated?

Where can I find the correct bootloader files for the CYPD3196?

Is it possible to reprogram the chip?

Hi,

CYPD3196 can be reprogrammed multiple times and SWD doesn't require or depend on any bootloader. 

I think you are not able to reprogram because you have programmed the IC with the wrong part firmware. Can you please try to erase the flash first using J-Link and try reprogramming it again.

For firmware and bootloaders of CYPD3196, you will have to contact local sales/FAE and get it as its confidential.

Best regards,

Thanks for the response.

Unfortunately I can't erase the flash because it is not even possible to connect to the chip. Is there anything else I can do to erase the flash and start from scratch?

Do you have any contact information for local sales/FAE?

Hi,

There is no other way other than erasing the flash and reprogramming. 
Regarding the local sales office, please locate the nearest office and contact them - https://www.infineon.com/cms/en/about-infineon/company/find-a-location/
