Critical Issue
After the JESD204C Intel® FPGA IP link is up in Intel® Stratix® 10 devices, if there is a warm reset applied to the IP, an unexpected tx_ready_err CSR register bit might be flagged right after the IP is reset.
This is due to the transceiver getting reset and tx_ready being deasserted after the mgmt_clk (avs_clk domain) is out of reset.
To work around this problem do either of the following:
- Clear the error interrupt.
- To avoid the interrupt, prolong the mgmt_clk (avs clk domain) reset when there is an IP reset to avoid errors being flagged during the reset period.
This problem is fixed starting from the Intel® Quartus® Prime Pro Edition Software version 19.3.
