Hello,
We have a custom board with two ad9361s and a Zynq. We have succesfully built BOOT.BINs and device tree for an "fmcomms2" which is able to find the ad9361 and all associated SPI devices (axi-ad9361, DDS, and phy). However when we try to create BOOT.BIN and devecetree for an "fmcomms5" to find both AD9361s we see the following messages while booting:
ad9361 spi1.0: ad9361_probe : enter (ad9361)
ad9361 spi1.0: ad9361_probe : Unsupported PRODUCT_ID 0xFF
ad9361 spi1.1: ad9361_probe : enter (ad9361)
ad9361 spi1.1: ad9361_probe : Unsupported PRODUCT_ID 0xFF
I have searched through previous threads to try to find the cause of this, but have been unsuccesfull. We are sure that the reset_b signal is connecte to the right pin, and we have checked the supply and reference voltages. What should we do to troubleshoot this issue. What are the causes for the PRODUCT_ID 0xFF
