7i76e_7i76x1_7i85sx2d.bit


I am trying to flash the 7i76e with this:;

cnc@Brix:~/Desktop$ mesaflash --device 7i76e --write 7i76e_7i76x1_7i85sx2d.bit

This is the error. No 7I76E board found

The bit file is on the desktop

I can ping the card on 10.10.10.10 with a time of 0.33
.
I have the latest version of mesaflash version 3.3.0 with sudo apt-get install mesaflash

try:

mesaflash --device 7i76e --addr 10.10.10.10 --write 7i76e_7i76x1_7i85sx2d.bit

I am not sure if I am doing this correct.

I have attempted to flash the 7i76e with:

mesaflash --device 7i76e --addr 10.10.10.10 --write 7i76e_7i76x1_7i85sx2d.bit

Then used: sudo mesaflash --addr 10.10.10.10 --device 7i76e --readhmid > mesa_7i76e.txt

This is the result:

File Attachment:

File Name: mesa_7i76e.txt
File Size:6 KB


I was expecting to see the encoder pins on the 7i85s but I don't see any reference to the 7i85s

I did this from a terminal on the desktop this is also where the bit file is. The mesa card seemed to flash ok and I did a power down & up before the read. Do I need to use sudo for the write?

Both expansion connectors have encoder connections, here's the first:

IO Connections for P1
Pin# I/O Pri. func Sec. func Chan Pin func Pin Dir
.......

Encoder connection for 4 axis of Multiplexed encoders:

7 27 IOPort MuxedQCountSel 0 MuxSel0 (Out)
8 28 IOPort MuxedQCount 0 MuxQ-A (In)
9 29 IOPort MuxedQCount 0 MuxQ-B (In)
10 30 IOPort MuxedQCount 0 MuxQ-IDX (In)
11 31 IOPort MuxedQCount 1 MuxQ-A (In)
12 32 IOPort MuxedQCount 1 MuxQ-B (In)
13 33 IOPort MuxedQCount 1 MuxQ-IDX (In)

Sorry I still don't see in hal configuration for the 7i85s I do see a 7i76 on the tree.
I can't find anything that relates to the 7i85s encoders so how do I know which physical pins to connect to on the 7i85s

There would be no 7I85S related pins, just encoders (and stepgens)

Well you certainly made me work on this one :cheer:

I had encoders=1 in the loadrt line in the hal file should have been encoders=5
Its all a learning curve, thanks for the help.
