Arria 10 partial reconfiguration thru JTAG debug mode time out. No way to program the partial reconfiguration .rbf file. Please help!

There are two Arria 10 devices in the JTAG chain. The partial reconfiguration IP has the JTAG debug mode enabled. Programming .sof succeeded, but when programming the .rbf file, the Quartus Pro 18.1 ...

​Hi John,

Thanks for quick answer. Assuming that the path from PCIe to Avalon memory interface is superfast and .rbf is not compressed, if PR Controller runs at 100MHz (that is the fastest it can run), can the time spent on programming the PR region thru Avalon memory interface be calculated as (.rbf file size in bytes / 4) * ( 1 / 100_000_000) seconds? The /4 is because PR Controller's Avalon memory interface is 32-bit wide. Or, even if PR controller is configured to use Avalon memory interface with JTAG debug mode disabled, will the PR programming thru Avalon memory interface still go thru an internal virtual JTAG that runs at only 6MHz so that the time spent shall be calculated as (.rbf file size in bytes * 8 bits) * (1/ 6_000_000) seconds ?

Thanks
