Other Parts Discussed in Thread: UCC5880QEVM-057,
Hello,
I am trying to interface UCC5880QEVM-057 Eval board with my custom board. I am interested in using addressed based SPI configuration. I am using McBSP Clock Stop mode to communicate with the gate driver.
Setup:
On the Eval board, J3-2 ,J3-3, J6 and J8 are connected for addressed based SPI. External GPIO is used to control INP to latch the address.
Process to verify the read operation. Not sure if write is being correctly executed as I cannot read from the GD chip.
1. After Power up Enter the addressing mode using 0xF809 command
2. Write Chip address using 0xFDA1, 1 is the chip address in this case.
3. Exit the addressing mode using 0xF80A command.
4. To Read the STATUS register sent the command 0x1112.
5. Added the NOP cycle to read from the chip.
Unfortunately, SDO output from GD is high impedance, Please see below serial trace.
Is there anything I am missing?
Thanks!
