nice summary.
FYI. I have since moved to Ubuntu 22.04. There are additional issues on this release relating to compiler problems during application build that will need worked out. I decided to just keep my Ubuntu 20.04 build available for now.

Re: XUF232-1024 stalls after software reboot
Sounds like an occasional timing issue, since it works most of the time. From the SPI, looks like tile[0] gets loaded correctly, but does not succeed to tile[4] over the xlink. Maybe: 1 - Increase the 3000uS delay longer. 2 - Slow down, if workable, the XLINK in your .XN file between the two chips. ...

Re: Inline assembler - making sense of operands
Yes save the lower 32 bits of the accumulator, then reload next pass into lower 32 and a zero in upper first thing. You can research using the "remainder" in a IIR. Also need to probably use A1/2 and/or B1/2, then use a double MACCS as most efficient. You will also need a ".Align 4&qu...

Re: Inline assembler - making sense of operands
You could just put the accumulator setup in a prior instruction, without needing to add operands to the MACCS. Seems more readable to me to separate things out. For an IIR on the X200 in assembly, you want to use indexing to access the parameters and feedback. So you need a structure (array for mult...

Re: Using 4-bit port for TDM on XU208
I would think you would implement the 4X TDM4_IN on your 4 one bit ports. This is probably fairly easy and low overhead as there is no need to multiplex the bits. But data rate is pretty high with TDM. Then the TDM4_OUT on the 4 bit port (lowest bit on the port if bit bang). I believe there are 2 op...

Re: Windows 10 Midi xCore-200 MC 2V0
My understanding, the Thesycon Eval driver will only enumerate with the XMOS PID's. Using a custom PID probably is using the Microsoft driver for the sound, but not MIDI.

Re: xTimeComposer on Ubuntu 20.04 Problem
ok, appears 20.04 has moved up to libtinfo.so.6.
Install the legacy version:
sudo apt-get install libtinfo5
xTimecomposer now sucessfully builds my application. xFlash also successfully built my binary.
Looks solved.

Re: xTimeComposer on Ubuntu 20.04 Problem
I was involved with the other tread also. Hmm... Didn't notice the newer reply. So removing ibpangocairo-1.0.so.0 also is needed. xTimecomposer now starts. But I am now having an error during build, though. /opt/XMOS/xTIMEcomposer/Community_14.4.1/libexec/xcc2clang: error while loading shared librar...

Re: xTimeComposer on Ubuntu 20.04 Problem
No updates. Still not working for me on 20.04.
Hopefully one of the team at XMOS upgrades to get this resolved.

Re: xTimeComposer on Ubuntu 20.04 Problem
Tried adding libtinfo5 libncurses5 pacakges on 20.04
still crash. I would think it is some dependency here.
Thanks for the reply.
