New Contributor10CL040YF484 Programming fails
Super ContributorHi Suvarna,
thanks for clarification about MSEL1. Didn't notice jumper resistor option. As you are supplying B6 with 3.3V, MSEL can be connected to 3.3V. 2.5V should be accepted as well.
Having configuration correct, I wonder what causes failure of your board. I would probably try without C160-163 and D10/11 to be sure that they don't interfer with AS configuration load.
Regarding 2.5 V switching regulator, I said I'd prefer LDO. it's exclusively loaded by VCCA and programming connector. Efficiency in normal operation is probably better for 3.3V supplied LDO. But your solution should work, too.
Regards
Frank
P.S.: I notice that Figure 99. Combining JTAG and AS Configuration Schemes also has 10 pF capacitors, but without additional series resistors.
New ContributorDear Sir,
Could you kindly check power section scehmatic for fpga. is it necessary to provide power sequencing?
pls tell us the final conclusion in our procured devives.

Hi Suvarna,
Let me check and get back to you.

Dear Sir,
please check hardware connections in ou1r design if any problem inform us since 3 boards are working perfect.other boards only problem. what about power sequencing is it necessary? in another mail also i gave replies.

Hell Suvarna, do you have further question?
