Occasional ContributorMAX 10 flash controller wrapping mode - non-functional
Hi,
From the SIgnalTap, I observed that you only provide read signal for 1 clock cycle when you are using burst count of 2. I would recommend you to provide read signal at least 2 clock cycle when you are using burstcount of 2 in wrapping mode.
Please refer to Figure 18 in https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/ug_m10_ufm.pdf
Occasional ContributorI forgot to include software versions.
I am running Quartus Lite 20.1.1 under Ubuntu 20.04.1 LTS. I have regenerated the ip this version.
A signal tap capture in vcd format is attached. As can be seen an address and request is provided by the data read stays at ffffffff. I verified that the flash has content, if I flash a sof in incremental mode it works.
So read data valid goes high, but no data...
Occasional ContributorI switched back to incremental mode and found that it no longer works on the latest ip either! However diffing the file I see this fix is not applied. It is also conspicuously within a burst mode=0 section, which leads me to believe there might be an equivalent needed for when burst mode is enabled.
