Hello all.
I try programming PGA450-q1 on SPI interfase.
I write firmware on keil and check it on evolution board. My firmware working correct.
I connected PGA450 with STM32 and try programming this device.
I switched off internall controller with 162F01 command and send byte array from hex file, after i switched on internall controller with 162F00 command.
But PGA450 not responded.
I try programming my board with TI-GER board and PGA450 responded.
After I try switching on and off PGA450 and was great result, it work.
But I can't programming this microsheme on SPI interfase.
I send data in format 0x1F ADRESS_HI ADRESS_LO DATA[i],
where 0x1F - command write to DEVRAM memory; ADRESS++; and DATA - it byte array.
Help me PLEASE
