hello @tooz, Ok. I'll find another way.
-
Is there a way to turn off the power supply to a USB device?
-
hello @tooz, I haven't measured the difference in power consumption yet, but I was able to disable the HDMI output. thx.

hello @tooz, Sorry. My explanation was insufficient. The file system is built within emmc and the microSD is used as storage for data. However, when a broken microSD is inserted, it outputs an error like the attached file and will not boot. When the microSD is removed and power is turned on, it boots up with no problem. Naturally, the pin setting is to boot in emmc mode. There is one partition in the microSD, which can be formatted. Therefore, I expect that some sectors are abnormal. I am using tinkerboard to send data to the server. At that time, I also send the status of the tinkerboard as well. Ultimately, I would like to be able to start the tinkerboard even if the microSD card is damaged, and to be able to tell the server that there is something wrong with the tinkerboard. Therefore, we would like to be able to boot the OS by emmc boot even if the microSD is damaged. dump.log

hello @tooz The following error message is displayed. Can't open display :0 I could not run it as root user. Does it have anything to do with the display being in CUI mode?

Hello. Tinkerboard R2.0 takes clock control when the CPU temperature exceeds 80 degrees. In other words, CPU throttling occurs. Is it possible to change the temperature?

Hello. I'm trying to reduce the power consumption of Tinkerboard R2.0 as much as possible. I was able to disable the HDMI output on the raspberry pi. Is the same possible with tinkerboard?
-
I'm running tinkerboard R2.0 with emmc boot. However, when the microSD is corrupted, it fails to boot. Maybe the microSD is checked when I start up, can I ignore it?

Hi @tooz 'iw phy' command is executed by root user. Attached is the result of the command executed on Tinkerboard and Tinkerboard R2.0. HT-PHY contents disappeared when migrated to Tinkerborad R2.0.

Tinkerboard R2.0 support HT-PHY? Tinkerboard could be used, but not in Tinkerboard R2.0. I can't find the HT-PHY item in the 'iw phy' command.
