Cannot flash Creator FPGA, Device failed to configure

Hello!

I’m currently trying to flash my own .bit file to the FPGA on the Matrix Creator, however I keep receiving “Device failed to configure” when running xc3sprog, here is the full output:

XC3SPROG (c) 2004-2011 xc3sprog project Rev: 774 OS: Linux

DNA is 0x5971f001ee64650c
Device failed to configure, INSTRUCTION_CAPTURE is 0x19

I’ve even tried flashing the original .bit file, but I get the same error. Using a Raspberry Pi 4 kernel version 5.4.79-v7l+ I just downgraded to this version from 5.10.11-v7l+ per a workaround for installing the matrix kernel modules, however both versions give me the same error.

EDIT: I followed the FPGA flashing instructions on this page: FPGA MATRIX
