Mesa 6i24 - Quad-IDXM? was created by risfutile
Hi there,
I have a Mesa 6i24 (that runs as 5i24 compatible) with the default firmware. The card is configured (at loadrt...) with 3 quadrature encoder channels (and 3 PWM channels) to interface to a 7i33.
The 7i33 is connected at P4 of the 6i24 and both the encoders and PWMs work well.
But on P2 I can't use IO 48..50, since they have "Quad-IDXM" functionality according to mesaflash --readhmi (output below).
These are not the index-pins of the encoder channels. Those are named "Quad-IDX" and are located at P4.
How do I get rid of these Quad-IDXM pins? Preferably without building and flashing an FPGA firmware.
I've made a custom PCB that gets connected to P2 and P3 and would love to use IO 49 and 50.
Cheers,
Michael

You would flash the 6I24 with:
5i24_16_svst4_8.bit (for a -16 card)
or
5i24_25_svst4_8.bit (for a -25 card)
using the mesaflash tool, for example:
sudo mesaflash --device 5i24 --write 5i24_16_svst4_8.bit
or
sudo mesaflash --device 5i24 --write 5i24_25_svst4_8.bit
5i24_16_svst4_8.bit (for a -16 card)
or
5i24_25_svst4_8.bit (for a -25 card)
using the mesaflash tool, for example:
sudo mesaflash --device 5i24 --write 5i24_16_svst4_8.bit
or
sudo mesaflash --device 5i24 --write 5i24_25_svst4_8.bit
