Configuring KSZ9897 Evaluation board over SPI
I am trying to configure the KSZ9897 Evaluation board using the MCP2210 USB to SPI bridge. To generate the SPI traffic I am using the MCP2210 SPI terminal provided by Microchip.
The IBA, MDIO and MDC jumpers to the USB port on ethernet port 7 are not set and the strap option LED4_1 for SPI is set to 1.
I am using a logic analyzer to evaluate the SPI signals from the MCP2210 in parallel to the inpu to the KSZ9897 Eval board.
On the logic analyzer the MCP2210 correctly outputs the SPI signals. I have tried both SPI type 0 and 3 at frequncies from 12 MHz to 10KHz.
The blue LED which is connected directly to the chip select lights up during a transfer, but otherwise the board doesn't react to either reads or writes.
I am shifting everything before the TA bits left 1 because of the 3 bit command / 5 bit TA.
So to read the ID register I am sending the SPI command 60 00 00 20 00.
Thank you for any help.
