Hello,

I have the CY8CKIT-145-40XX kit, I would like to use two uart.


In Schematic the first one is connected to kitprog2 pin P3.1 TX and P3.0 RX,

and the second one is connected to proc BLE pin P0.5 TX and P0.4 RX.
But I can not configure the pins of the two SCBs in PSOC 4, and I have the following error.
FFB and IO placement failed: Failed to find a valid placement for \ PC: SCB \.  where PC is the name of the first  SCB.

Any help?

Thanks in avance

Hi, Fausto

PROBLEM: USING TWO UART COMMUNICATIONS IN A SCB BLOCK

1. You used two UART communications in a common SCB block(scb[1])

2. You must use another SCB block(scb[0]) as shown in the below table. Drags and drop a new SCB block and assigns pins appropriately corresponding the below.

3. Although assigns new pins for a new UART, you couldn't use the UART communication with UART pins of PROC now that it is not connected with the UART pins of PROC electrically for NO LOAD(open status). so you must externally connect to the UART pins of PROC from the your assigned new UART pins

please let me know whenever you need my help.

Thanks,

OK, I connect pins 1.0,1.1 to another uart/usb converter and pins 

0.4,0.5 to proc ble.

Tanks for all.

Best Regards

Fausto
