Hi there, I have a little problem with my i2c-screen on the Helios4. It was setup according to the Kobol-Wiki and was working right from the start. However after running for some time (in this example it took around 6 hours) the screen is black and empty. Once I SSH back into the helios and restart the systemd sys-oled.service, it works again for some time... "journalctl -u sys-oled.service" gives the following: Sep 13 10:18:38 helios4 systemd[1]: Started System Starting on OLED Display. Sep 13 16:46:01 helios4 python3[23009]: Traceback (most recent call last): Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/bin/sys-oled", line 158, in <module> Sep 13 16:46:01 helios4 python3[23009]: main() Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/bin/sys-oled", line 148, in main Sep 13 16:46:01 helios4 python3[23009]: display_info(device) Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/bin/sys-oled", line 130, in display_info Sep 13 16:46:01 helios4 python3[23009]: draw.text((0, 27), network(net_name), font=font, fill="white") Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/lib/python3.7/dist-packages/luma/core/render.py", line 43, in __exit__ Sep 13 16:46:01 helios4 python3[23009]: self.device.display(self.image) Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/lib/python3.7/dist-packages/luma/oled/device/__init__.py", line 114, in display Sep 13 16:46:01 helios4 python3[23009]: self.command(set_page_address, 0x02, 0x10) Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/lib/python3.7/dist-packages/luma/core/device.py", line 48, in command Sep 13 16:46:01 helios4 python3[23009]: self._serial_interface.command(*cmd) Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/lib/python3.7/dist-packages/luma/core/interface/serial.py", line 91, in command Sep 13 16:46:01 helios4 python3[23009]: list(cmd)) Sep 13 16:46:01 helios4 python3[23009]: File "/usr/local/lib/python3.7/dist-packages/smbus2/smbus2.py", line 643, in write_i2c_block_data Sep 13 16:46:01 helios4 python3[23009]: ioctl(self.fd, I2C_SMBUS, msg) Sep 13 16:46:01 helios4 python3[23009]: TimeoutError: [Errno 110] Connection timed out Sep 13 16:46:01 helios4 systemd[1]: sys-oled.service: Main process exited, code=exited, status=1/FAILURE Sep 13 16:46:01 helios4 systemd[1]: sys-oled.service: Failed with result 'exit-code'.

Aaah ok, now I get it. You referred to the MV3720.. That makes sense. Thanks for the update!

Strangely when running a `cryptsetup benchmark` I can see that the interrupt is triggered: Doesn't that mean that it's using CESA? Also, I wonder why there is no interrupt activity on 49 but just on 48. Seems the distribution to both CPUs is not working..?

Thanks for the info!

Thanks! That means, it makes no sense to even use aes-cbc-essiv:sha256 anymore. Kobol Team is out of business so there will be no fix regarding this... I guess I'll do a cryptsetup benchmark and just use the fastest cipher it finds.

Hi, any news about this? It states in the wiki: Will there still be work on "your" side, given that the model seems to be End-of-Life? If not, is there any way we could still make it work? I would take the risk, especially since the wiki provides a recovery method....

Double post, sorry. (Why can't I delete my own posts?)

I don't understand this exatly. The poster above you found these values: - Plain access to disk: 180MB/s - LUKS2 + CESA: 140MB/s - LUKS2 (no CESA): 52MB/s So I wonder how/why you think not using CESA is better here. From my point of view this seems to be a contradiction. Or is there something I don't see?

I should add, that I'm using the NAS for storing large files that are almost only written, medium files that are written once and read from time to time, and small files that are read and written often..

Hi there, I have a Helios 4 (last batch) and just wanted to ask if CESA is still not functional with the current Buster release? I'm in the midst of a new setup and wonder if I should even try to use CESA. Also one question for clarification: Here in the forums, but also in the Kool-wiki, I it seems to me, that people are saying that CPU crypto is superior to CESA in terms of performance... As I'm quite noobish regarding this, I would be very grateful for any recommendations. Thanks in advance!
