03:21 <balrog> where is the GPL for the TM-AC1900, at least the firmware versions that were supported?

03:22 <balrog> If they're not gonna support it anymore, they should at least provide a GPL, so we know what stuff to disable

03:22 <balrog> (in order to not violate licensing)

03:22 <balrog> and also because, well, they have to release GPL by law

04:28 <Ultrasauce> balrog: asuswrt-merlin?

04:28 <balrog> Ultrasauce: yeah, wrong channel oops :)

05:15 <emeb_mac> tnt: ping

05:18 <tnt> emeb_mac: pong

05:19 <emeb_mac> tnt: I was hunting thru your ice40 playground to find the usb bootloader for up5k - is it there or somewhere else?

05:19 <tnt> yeah

05:20 <tnt> The 'riscv_usb' project

05:21 <emeb_mac> ah ok. saw that but saw some comments about having to use serial interface to start it up.

05:22 <tnt> (and the 'boot_stub' project, they work together. You flash the boot_stub as the default multi-boot image and the 'riscv_usb' project as the second image. App bitstream will be the third image, see some comment in boot_strub for the flash layout)

05:22 <emeb_mac> cool. thx.

05:24 <tnt> emeb_mac: you need to be in the `usb` branch. And the `fw_dfu.c` software auto-enables usb and is the one containing the DFU/bootloader firmware.

05:24 <emeb_mac> tnt: excellent. I'll give that a try on my up5k board.

05:25 <emeb_mac> (which has a usb connection)

05:26 <tnt> So you'll need `make BOOT_CODE=dfu prog` in the base dir to build the hardware with the hardcoded flash offsets to load software from the 'dfu bootloader' part of the flash and then `make prog_dfu` in the `fw` directory to flash the riscv sofware at the right addess.

05:27 <tnt> err my bad. the `make prog` won't work, it won't flash it at the right place.

05:28 <emeb_mac> ok. we'll see if I'm smart enough to figure all that out. :)

05:29 <tnt> the easiest is to build boot_stub, the hardware for the usb bootloader (making sure to use BOOT_CODE=dfu) and the software for the bootloader and then use the script in bootstub (mkmultiboot.py) to combine the whole thing in a single multiboot image you can flash as a whole.

05:31 <emeb_mac> ok - saw that python script and assumed it was key

05:33 <tnt> just pay attention than its arguments are each 'group' of images, with hw/sw separated by colon (:) so you'll have somehting like `mkmultiboot.py boot_stub.bin riscv_usb.bin:fw_dfu.bin`

05:33 <emeb_mac> seems easy enough

05:52 <emeb_mac> gah - my git fu is not strong. did a git checkout usb but the fw directory still seems to have the master stuff in it - missing all the dfu stuff

05:54 <tnt> what does git status say ?

05:57 <emeb_mac> https://pastebin.com/ZpcEYQDV

05:57 <tnt> git log ?

05:59 <emeb_mac> https://pastebin.com/LSU4psdk

06:02 <tnt> Ok, so you created a branch you named 'usb' locally but it points to the master branch of the repo.

06:02 <tnt> just do `git reset --hard origin/usb`

06:02 <tnt> (this will erase any local change)

06:02 <emeb_mac> ok - thanks

06:03 <emeb_mac> that did it.

06:03 <emeb_mac> as I said - weak git skills. :P

06:17 <emeb_mac> seems I have a multiboot bin now - will play with this tomorrow. will need to tweak the pin mappings.

07:34 <keesj> https://ohshitgit.com/

07:36 <keesj> and on the positive side https://learngitbranching.js.org/ is a fun way to learn git foo

16:44 <jevinskie[m]> I thought this channel might find this interesting: it’s the compression and decompression algorithm for the simple altera bitstream compression. It just takes each 16 bit word in the bitstream, outputs a nibble with a bit set for each non-zero nibble in the word, and then the non-zero nibbles themselves https://gist.github.com/jevinskie/a4ed8a6337e791a07b412a5be9f132af

16:48 <qu1j0t3> cute

16:53 <Lofty> Oh, hey jevinskie[m]

16:53 <Lofty> Might want to join #prjmistral ;)

17:23 <tpw_rules> isn't that how stuffit worked or something

17:26 <qu1j0t3> i think stuffit was lzw-like

17:26 <qu1j0t3> i.e. dictionary
