PGA450-Q1: Programming and Testing Issue

Rohith Ravikumar

Part Number: PGA450-Q1

Hi,

After OTP programming the PGA 450 IC, we are able to get the UART response from command 0 (0x12 0x34), but we are unable to get any burst data from Command 1 through UART.

We have verified the SPI EEPROM registers and OTP Programming status. We used the Demo code provided (PGA450Q1EVMSUARTLINDemo-2.9) to program the OTP.

Please suggest us any debugging options.

Hi Rohith,

Please note that only commands 0, 2, 4, and 6 actually returns data to the MCU. Command 1 performs a time of flight execution, but you need to follow-up with command 2 to get the time of flight result that command 1 generates. The below post has some more details:
