| xobs | CarlFK: "Kind of." | 02:47 |
|---|---|---|
| xobs | What are you wanting to do use it with? | 02:48 |
| xobs | Many JTAG boxes have voltage conversion, if the PCB is running at a different voltage. For example, many modern Xilinx parts run at 1.8V, which will need an adapter. | 02:49 |
| xobs | But if VDD is 3.3V (ish) on the device you want to debug, then yes you can use openocd to bit-bang JTAG (or SWD). It's what we do with Tomu, and it's what we do (with a level shifter) for NeTV2 and Betrusted. | 02:50 |

| CarlFK | xobs: given pi's are popular, I was wondering if it could be used 'generally' and sounds like no, or "it depends" and if no one knows, then no. | 05:13 |
| xobs | I always use them in the factory to program my boards, because they're cheap and most chips I work on are 3.3V. Most hobbyist projects are also 3.3V. 1.8V stuff is common in industry, but for now hobbyist projects will be safe using a pi. | 05:15 |

| somlo | _florent_: should I be able to use any fat fs (particularly the more typical fat32) with sdcard and the litex bios now ? | 17:16 |
| somlo | guess I'll format a sdcard with fat32 and try, see what happens :) | 17:17 |
| CarlFK | have a fire extinguisher handy | 17:19 |
| npcomp | Further readins seems to suggest that the CLE-215 is _exactly_ the nitefury? | 17:41 |
| somlo | _florent_: building the bios `--with-sdcard` is broken right now -- undefined symbols such as `disk_status`, `disk_read`, etc. that are only currently provided in `spisdcard.c`, and not in `sdcard.c` | 17:41 |
| zyp | npcomp, my understanding too | 18:18 |

| npcomp | Realizing I am new to this type of development, I was considering what neat things might be available with this type of dynamic pci device. One of the ideas I had was having the pci device offer an option rom, like a network card. | 18:48 |
| CarlFK | npcomp: friend works for www.m-cubed.com - they take used servers that have been "tweaked" and puts them back to OEM stock because that is easier to sell. ... | 19:56 |
| CarlFK | 19:56 | |
| CarlFK | one of the tasks is "hacking" the current bios eprom whatever and getting it flashed? back to stock | 19:57 |
| CarlFK | maybe a pci card that halts the boot/post/whatever process and gives you a busybox prompt | 19:58 |
| CarlFK | netv2 has hdmi out and eathernet. | 19:59 |
| _florent_ | somlo: sorry i haven't adapted the litesdcard code yet, FatFs has only been tested with spisdcard, i was planning to also add litesdcard support next week | 20:05 |
| somlo | _florent_: ok, no worries, I still have the last nexys4ddr bitstream from before that change (built for sdcard), so I'll use that for testing with 64-bit kernel patches | 20:08 |
| somlo | (and I can check out earlier commits, if push comes to shove :) | 20:09 |
| somlo | as long as it's on your radar, it's not a huge emergency or anything | 20:09 |
