Hello I'm Using Cypress CY8C4247LQI-BL483 Microcontroller and trying to Configure Full UART : UART(SCB Mode)v3.0 in UART Configuration .
After Building the Code : Following Errors Were occurred .
""Unable to find a valid placements for Pins and Fixed-Functional Blocks . See the Digital Placements’s Detailed placement Messages Section in the report file for Details ""
Compiler Suggested Following Workaround .
The placer is not able to place all of the carry chains without backtracking. It fills one UDB bank to 15/16 and the other to 7/8 and cannot place the final
2-datapath chain. As a workaround, add a control file to the TopDesign component (in Workspace Explorer's Components tab) with the following lines: ATTRIBUTE
placement_force OF \Timer_ADPActiveTime:TimerUDB:sT16:timerdp:u0\ : LABEL IS "U(2,0)";
ATTRIBUTE placement_force OF \Timer_OutputPeriod:TimerUDB:sT24:timerdp:u0\ : LABEL IS "U(3,1)";
ATTRIBUTE placement_force OF \Timer_OutputActiveTime:TimerUDB:sT24:timerdp:u0\ : LABEL IS "U(0,1)";
This will fill the datapaths in the second UDB bank and allow the placer to assign the remaining datapaths.
I Followed the Instruction and created a Control File and added above mentioned three lines . : After Built Same Error were Observed.
Please Suggest me What Should I do . As I want to Use Both Tx and Rx Interrupt Enabled , With API Settable Baud Rate and Parity .
