MSEL wrong configuration

Hello, I designed a board using a EP4CE22F17C6N and I made a wrong connection on MSEL. I put it on MSEL[2..0] 001 instead of MSEL[2..0] 010. Besides the high level is tied to VCCio e.g 3,3V in...

Hi,

I have a similar issue with a Cyclone IV "EP4CE15M8I7N".

I have (accidentally set MSEL[2..0] = 001 which is an invalid setting (Not in the selection table in the datasheet).

When I try to use JTAG, I get this message: "Error (209014): CONF_DONE pin failed to go high in device 1"

According to datasheet (Notes to Table 8-5): Connect MSEL to VCCA or GND. So JTAG should technically work regardless of this setting.

Can anyone confirm that the MSEL[2..0] = 001 would cause this issue?

Is there a workaround as the BGA has extremely fine pitch and almost impossible to re-work.

I have checked the CONF_DONE pin and it never goes high.

JTAG device can read the device ID without any issues.

Many Thanks.
