Other Parts Discussed in Thread: AFE7950
I am working on configuring the AFE7950EVM + ZCU102 setup, where both the LMK and AFE7950 are being configured through the FPGA. I need your support regarding a few points, which I have listed below:
-
SPI Communication:
The LMK and AFE7950 SPI communications are functioning correctly. Also, the current drawn during configuration via the GUI matches the current observed when configuring the AFE7950EVM through the FPGA. -
LMK Clock Issue:
The 491.52-MHz LMK clock is currently not being generated. I will attach the relevant register details for your reference. -
AFE7950 Reset Sequence:
For resetting the AFE7950, I am using the sequence provided in the TI secure folder (the C code in tiAfe79_interface.c). Please confirm whether this sequence is sufficient for proper device configuration. I will also attach the main.c file showing the steps I am following. -
JESD Reset Connections:
I have connected the JESD_RSTn and JESD_TXRST pins to the master_reset_n, tx_reset_n, and rx_reset_n signals respectively in the TI_204c_IP_ref.sv file.main.c spiwrites_lmk.c spiwrites_AFE.c I kindly request you to review the above points and confirm whether the procedures are correct.
Thank you, and I look forward to your feedback. Thanks & RegardsGuruthathathreya S
