We are running into a program not being able to connect to a CY8C624AAZI-S2D44 on a new PCB we have recently used the CY8C624AAZI-S2D14 and did not have any issues. Both devices are setup the same hardware wise using a Miniprog4 and cypress programmer. From what we know the only difference between the two devices is the crypto accelerator. Can anyone provide any insight why we are unable to connect to the S2D44 version? Does the .hex file have anything to do with the connection steps?

Hi @jrobinson ,

A few basic checks:

1. Is the device supplied power? (You need to supply 3.3V on VDD)

2. Is the reset mode set to XRES?

I tried it at my end, and it worked properly. So, if it is a custom PCB - supply power to the device while programming or else follow steps in the above screenshot.

Let us know if this resolves the issue.

Warm regards,
