From AM335X Technical Reference Manual Table 9-1. Pad control register filed descriptions, we can get bit 3 meaning. 0 pullup/pulldown disable 1 pullup/pulldown enable But from uboot and kenel codes we can get #define PULLUDEN (0x0 << 3) /* Pull up or…

Hi，as shown in the figure，lab 1 to 4 are all aimed at verifying the PFC mode.
However, why did lab 1 and 2 use DC as the input, rather than AC voltage?

When the control card is not inserted into the tdim-02013, the GPIO port can detect the output PWM waveform. When the control card is inserted, the voltage across C164 is measured, but no voltage PWM signal can be detected.…
你好，参考下工程师的回复：
With AC input it works as a PFC input stage. It boosts the input volt to generate a higher DC bus volt and shapes the input current. This is average current mode control (ACMC) AC/DC boost.
But for DC input, it will be the same except that…
