  1. That newsletter indicated that USB-C to HDMI cables promised were still delayed. Is there an update on that? Thanks!
  2. I did not have to shave the USB C serial console cable so I assumed I would not need to shave the others. Might have been a mistake. I will find my box cutter and do a little remodeling on the cable and report back. Thank you for your reply!
  3. OK, I am confused. On mainline kernel as shipped does video over USB C work or not? When I plug in a USB C to display port adapter I get : [ 971.601581] cdn-dp fec00000.dp: [drm:cdn_dp_pd_event_work [rockchipdrm]] Not connected. Disabling cdn [ 971.604655] cdn-dp fec00000.dp: [drm:cdn_dp_pd_event_work [rockchipdrm]] Not connected.

  4. You should be able to just create a file 90-helios64-hwmon.rules in the /etc/udev/rules.d/ directory with the above text and reboot and it will create the /dev/fan* entries for you. That worked for me.
  5. The /dev/fan* entries should be created by the included udev rules. In particular: cat 90-helios64-hwmon.rules # Helios64 persistent hwmon ACTION=="remove", GOTO="helios64_hwmon_end" # KERNELS=="p6-fan", SUBSYSTEMS=="platform", ENV{_HELIOS64_FAN_}="p6", ENV{_IS_HELIOS64_FAN_}="1", ENV{IS_HELIOS64_HWMON}="1" KERNELS=="p7-fan", SUBSYSTEMS=="platform", ENV{_HELIOS64_FAN_}="p7", ENV{_IS_HELIOS64_FAN_}="1", ENV{IS_HELIOS64_HWMON}="1" KERNELS=="2-004c", SUBSYSTEMS=="i2c", DRIVERS=="lm75", ENV{IS_HELIOS64_HWMON}="1" SUBSYSTEM!="hwmon", GOTO="helios64_hwmon_en
  6. Thanks for the info but I have pwm_fan loaded but no /dev/fan* devices.
  7. As I am (as usual) doing something slightly different can someone tell me what module (or whatever) needs to me loaded to cause the /dev/fan* devices to exist? Thanks in advance!
  8. First of all thank you so much for the link to a working 2gb uboot. I just grabbed it and got my 2gb back. Second, I had noticed earlier in the day that on the espressobin download page aht all the uboots had been updated as of 8/24/2020. I tried ALL of the ones listed as 2gb and ALL of them still came up as 1gb, so whatever fix was put in did not take. But as I say, the link above to a working 2gb uboot got me going again.
  9. Hi, my helios4 was not running when I cam in this morning. When I cycle power all I get is : BootROM - 1.73 Booting from MMC Card did not respond to voltage select! Error initializing MMC - FFFFFFEF Trying Uart and nothing else. I tried leaving it powered off for an hour and tried again and I get the same thing. Any suggestions? Thanks, Tim Krantz UPDATE! I finally got the idea to eject and re-insert the micro-sd card and now all is well. Have I mentioned how much I love this litt
  10. I measured at t points referenced above. I got 12.69 at C18. At C34 I got 0.0. Now I am going to admit I am not that good with that particular kind of stuff. I could have been doing something improperly. If there is something else I can test for you I am glad to try it. I will also admit that I tried to get a reading from the pins inside the plug as well but my hands are just not steady enough and I could never get a reading.
  11. I had a meter. I have not seen it lately. If I can't find it I will go get one. Thanks for the reply. I apologize for my petulant tone. There was NO need for that.
  12. Received my board. Got it booting from the SD card without building the kit. Was running fine. Halted it. Assembled the entire kit following the WIKI instructions to the letter. Applied power and nothing, no LED's no fans no disk power up, nothing. Stripped it down the the board only, completely removed from the kit, applied power and nothing. Nothing on the serial console. Had a lovely chat with someone who gave me some suggestions. I will report back here my progress.
