How do teams automatically power on their jetson (tk1 or tx1) co-processors? We’re worried that we’ll forget to hit the power button before a match.
I’ve read Marshall (Team 0900) recommends this. I’m not sure if this automatically boots the TX1 or not.
Also, this thread may help.
I apologize for not being more help, but we have yet to make a decision about purchasing a TX1 or not so I can only regurgitate the information I have read.
We used a tk1 last year (until we accidental fried it). We experimented with a lot of things because the board would sometimes automatically turn on, and sometimes wouldn’t. We followed the instructions in this thread:
Please try removing 0.014F capacitor (C6D4 part) on PMIC’s VBAT_BKUP pin on Jetson if you have a soldering iron.
Basically the 0.014F capacitor is keeping +2.5V_AON_RTC signal high for hours to keep PMIC’s AC_OK (pin to indicate that the AC adaptor is present) high when cord is plugged out.
Removing the capacitor help PMIC to recognize AC adaptor plug out soon and plug in the cord shortly after plug out will make PMIC to initiate power up cycle automatically.
This helped most of the time, but a better solution would be to throw an arduino on it that ‘presses’ the power button automatically.
