Dec 10 07:13:42 <Mahaboob> Frimware binary file (am335x-pru0-fw)is not found, After configuring the pins p8.15 and p8.16 using config-pin utility.
Dec 10 07:14:23 <Mahaboob> Frimware binary file location /lib/firmware
Dec 10 07:32:40 <zmatt> Mahaboob: config-pin has no relevance on the presence of absence of files
Dec 10 07:41:17 <zmatt> i.e. it's not possible for configuring pins to have caused a firmware file to somehow go missing
Dec 10 07:45:21 <zmatt> what firmware were you expecting to be there anyway?  it sounded to me like you're trying to write pru software, so in that case you're the one that needs to supply the firmware file
Dec 10 13:07:19 <Mahaboob> I tried copying .out file to /lib/firmware/am335x-pru0-fw.

Dec 10 17:52:24 <fusitni> zmatt: hello, jason told me that you have UIO working on the AI.  The Bela team is trying to get their PRU code working on the AI but they were using uio_pruss
Dec 10 17:56:46 <drew_fustini[m]> jkridner: hi, finally joined riot
Dec 10 17:57:21 <drew_fustini[m]> been a long time since i was active with irssi always open on my N900 :)
Dec 10 17:57:32 <drew_fustini[m]> rcn-ee: you are here too i see
Dec 10 17:57:36 <drew_fustini[m]> @zm
Dec 10 17:58:09 <drew_fustini[m]>  * zmatt: hello, I was told this was the best place to chat about uio and the AI
Dec 10 19:09:00 <zmatt> drew_fustini[m]: yo
Dec 10 19:09:45 <zmatt> drew_fustini[m]: yeah py-uio works on both am335x and am572x
Dec 10 19:13:44 <zmatt> libprussdrv probably would work too, but if both pruss instances are configured for uio then libprussdrv would only be able to use the first instance (or more specifically it just assumes /dev/uio0-7 are the relevant devices, which is pretty gross)
Dec 10 19:16:18 <zmatt> if it's desired to use both instances then you could either fix up libprussdrv (shovel all the globals into a context struct and add a mechanism for selecting the instance) or use py-uio to perform setup (including firmware loading) and just use open()+mmap() on the C/C++ side
Dec 10 19:19:38 <zmatt> drew_fustini[m]: the installation instructions in the py-uio README ( https://github.com/mvduin/py-uio ) include links to a suitable DT fragment for uio-pruss on am572x along with an udev rule to create symlinks that make it easy to find the correct devices (so you don't need to search or guess which /dev/uio* is what)
Dec 10 23:04:34 <drew_fustini[m]> thanks
Dec 11 01:45:40 <bbusted> Hi, I just flashed a BBB using the standard procedure. On reboot(without SD) it connects but gives me "Failed to write to 'state.settings'. ENOSPC: no space left on device".
Dec 11 02:38:07 <WanaGo> @set_ thanks for the info you sent to my LCD question. However the LCD CAPE's I am referring to are like the original CircuitCo offerings, or the 4D Systems offerings. They have been working on the BBB and BBBW and BBG for some years now, but I cannot figure out how to get them working on the BBAI, which makes me think their is lower level stuff
Dec 11 02:38:08 <WanaGo> which is not ready to support LCD Capes.
Dec 11 02:41:33 <bbusted> further investigations.. ssh into the BBB and df -H is giving me a /dev/mmcblk1p1 100% used. Strange because I expected to see a mmcblk0p1 because, 1p1 indicates SD drive. Like its thinks its connected.
Dec 11 02:45:10 <set_> Oh.
Dec 11 02:46:47 <set_> WanaGo: I personally have not used the CircuitCo.  LCD Cape yet but there is a different pin out for the am5729 compared to the other am335x or OSD335x.
Dec 11 02:47:50 <set_> On that page I referenced, that github repo. wiki, it shows exactly what pins are which that are available.
Dec 11 02:47:51 <set_> ...
Dec 11 02:49:41 <set_> For instance: If P9.14, 16, 23 were used for the connection for LCD displays for the am335x, one might need to start on what do those pins exactly represent on the am335x. Then, one could go to the am5729 and use that instead.
Dec 11 02:49:42 <set_> ...
Dec 11 02:49:47 <set_> Does that make sense?
Dec 11 02:51:09 <set_> There is a pinout given by @zmatt I can show you for the am335x. This may help: https://docs.google.com/spreadsheets/d/1mSqEpV_BAUHfeNApytxHcGhgTZwypy564GyOr66Nphs/edit?usp=sharing.
Dec 11 02:51:46 <set_> WanaGo: What pins do the Circuit Co. LCD Cape use?
Dec 11 02:52:48 <set_> https://docs.google.com/spreadsheets/d/1mSqEpV_BAUHfeNApytxHcGhgTZwypy564GyOr66Nphs/edit?usp=sharing <<<<< Use this instead of the last link I provided.
Dec 11 02:54:53 <set_> I can go and look up/research the idea of 4D Systems LCD Cape right now. Please reply when you have time.
