Occasional Contributor[Arria 10SX] Fail to load QSPI flash using quartus_hps
Dear all,
I have a simple design using the HPS on an Arria 10 AS048. The HPS is only present to load the PL configuration at boot time using u-boot.

Occasional ContributorHi,
Yes this is a custom board.
The quartus_hps commands in the document are the ones I am using.
It seems a solution to this is to reduce the JTAG clock speed using :
$ jtagconfig --setparam 1 JtagClock 12M
I could then run quartus_hps to program u-boot image in the Flash with no problem several times.
However it considerably slows down the programming.
Regarding jtagconfig command, I saw that setting the JtagClock to 12M actually results to a value of 6M (based on the output of a following "jtagconfig --getparam 1 JtagClock"). If I set the value to 6M, it is effectively set to 6M.
Is that a known problem? Please note that I use USB Blaster II with quartus 18.0.
