7i90 in SPI mode, bitfiles from http://www.mesanet.com/software/parallel/7i90.zi was created by rmu
I just got my brand-new 7i90s and managed to hook it up to a raspberry pi via SPI. Secondary config came pre-flashed with SPI config. Compiled mesaflash (got it from github), downloaded www.mesanet.com/software/parallel/7i90.zip (the link is from the store). I noticed that the configuration is for a stepper, I need servo, plus smart serial, so I tried to flash another firmware in the primary location. That seems to have worked, but output from readhmid did not change!

So I tried some different firmware files (justio, the dual 7i48 config etc...) only to find that I always seem to get the same readhmid.

Next thing I diffed the bitfiles (with vbindiff), and it seems, the SPI bitfiles only differ in the build time, the rest is identical. I.e. it is possible to flash the justio bitfile and verify with 7i90_spi_sv12im_2x7i48.bit and it compares OK.

I did not check all SPI bitfiles, but I noticed that e.g. 7i90_epp_justio.bit and 7i90_epp_sv12im_2x7i48.bit are very "different", i.e. they differ not only in the build date/time.

Next thing I will try to rebuild the bitfiles, but it will take some time as I have zero recent experience with anything FPGA, and that beast of xilinx software refused to download completely...

I'm pretty sure something is fishy with the spi bitfiles. Any help appreciated.

EDIT: I did change the jumper from secondary EEPROM to primary after booting.

Update: found ssst8_6.zip on this forum, flashed that, output of readhmid says 6 StepGens on P1 and Smart Serial on P3. So flashing works.

I'll update the batch file and rebuild the bitfiles in case there was an issue with the batch file that built these

So I managed to build SVSS6_8_72 with spi and flash it, readhmid seems to be ok.

I was under the impression that mesaflash --sserial should give some info of connected smart serial boards, but connected 7i90s with factory-flashed SSerial Remote firmware don't show up. /INIT and PWR LEDs are on.

Also tried EPP-version of SVSS6_8_72 as supplied in 7i90.zip, no difference, with multiple different CAT5/6 cables that do work as gigabit patch cables. 50pin cables are former SCSI cables that did work when last in use (a decade ago). With the scope, there is no activity to see on any tx-pins when idle nor when runnig --sserial.

Testing with 7i90_epp_svss6_6.bit I do see some activity on the TX-Pins on the scope, but of course pinout is not suitable for 7i44 breakout board.

Probably I'm missing something trivial, but I don't see it.

Those indicate that the 7I90 sserial remotes were found and are working

I believe I fixed the build batchfile and have updated the SPI configs in 7i90.zip

The strange thing is that mesaflash --sserial shows those boards only after running/connecting with the linuxcnc hostmot2 driver. Directly after power up, no sserial boards are recognized / reported.

Will try new 7i90 builds tomorrow. Thanks.

Its entirely possible that there are _many_ bugs in Mesaflash's SPI interfaced functions
and LinuxCNC's SPI driver (I know there is an interaction between them perhaps the spidev SPI driver state
or something)

I would try a simple hal config and toggle some 7I90-ssremote I/O bits
(halcmd show pin to get a pin list)
