Hi all,
I am having a very strange problem with UART communication, and I have spent a lot of time trying to find a reason for it. I am using the UART component (v2.5 and PSoC Creator 3.2) in full duplex, with flow control enabled and only the 4 byte hw buffer.
I have just made a new batch of my pcb and none of them are doing what they are supposed to do. Fortunately I had 2 older PSoC4's laying around for an older prototype, and mounting them on the PCB works just fine. There naming is "CY8C4245AXI-483 1431 A 04" and the none working units have "CY8C4245AXI-483 1525 C 32".
Anyone of you had similar problems? any critical silicon change that im unaware of? I know this is a risky judgment, but it is currently where I am, my design is pretty mature.
It is like the UART hw buffers simply is not working the same way anymore. If I enable software buffer I see better behavior, but it is not an option for me right now. And I would like an explanation for this phenomenon.
Thanks in advance.
Regards
Dennis
