New ContributorDual Configuration IP on MAX10
Regular ContributorHi,
Just would like to confirm if all the board is program with the same pof file?
Are you able to configure to Image1 during power on using external CONFIG_SEL pin?
New ContributorHi,
yes it is the same pof file and I can change to Image 1 with the config_sel pin at startup.
I also tested it with writing the config_sel=1 and config_sel_overwrite=0 to just triggering the rconfig.
On the good boards I read the input_reg with 0 because of the reconfiguration and on the three that do not reconfigure I still read config_sel=1...
Because of your last post I added just one additional state for the busy checking.
- addr="000", writedata = "01"
- addr="000", writedata = "01", write='1' (triggering the reconfiguration)
- addr="011", read='1'
- addr="011", read='1' <-- added
- addr="011", read='1' and wait till readdata(0) is '0'
Still it never gets busy (readdata(0) is always zero), but now it does the reconfiguration. I actually don't understand why.
Is it necessary to check the busy after writing to Offset 0? Can any operations after the triggering of the reconfiguration "abort" the reconfig?
