GPIO connection with any external I/O pins for ADRV1CRR FMC Carrier Board

Category: Hardware
Product Number: ad9361-z7035, ad9361

Hi,

I'm working on ADRV9361-Z7035 using PicoZed SDR FMC Carrier Card. I have built my RTL core inside the "axi_ad9361.v". I was successfully able to get some RTL check points connected out to the GPIO pins available at the BOB board pad area P2 or P13, and check those signals on the oscilloscope, based on your valuable response on following thread

Internal GPIO connection to any pins of P2 or P13 for ADRV9361-Z7035 BOB Carrier Board - Q&A - FPGA Reference Designs - EngineerZone (analog.com)

Currently, I'm working with the bigger ADRV1CRR FMC carrier board and I need to be able to get some RTL design points out, Could you please help me on how do so?

Thanks,
Hatem

  • Hi, 

    Sorry for late reply No I don't have updates yet. Actually, the concept was to interconnect and control with external power amplifier and switch selector to extend the coverage range of antennas.

    So, the idea was to provide this via the IN/OUT GPIO pins of the BOB carrier, where the ADRV1CRR-BOB carrier provides 162 user I/O pins for easy access to the SOM I/O. I was wondering If this option is also available via the ADRV1CRR-FMC carrier. Either through the FMC mezzanine card or on-board switches. If so, the question was what are tcl files should I update to do such connection on project building.

    I've one more question related to passing long input variables via python script into the ARM cortex A9 processor. Regularly I use the one of the SPI 32 registers to send data using command reg_write(0x800000BC, digital_value). Now I need to send a key of 256 bits is their a way to use multiple registers instead of splitting the value into 8 subsequent writes.

    Thanks in advance for your care to follow my progress status.
