For many engineers, using various tools become everyday job, sometimes we even miss in those tools. In the article, the author went through one experience of solving routing congestion in the design t
I put my 6410 into hibernation and then woke it up. For less than 1 second, the screen showed the image before it went into hibernation. It seems that the video memory was not refreshed and the backli
Using vivi, it shows booting the kernel but nothing happens: The details are as follows vivi> boot Copy linux kernel from 0x00030000 to 0x30008000, size = 0x001d0000 ... done zImage magic = 0x016f2818
Since the clocks of the transmitting and receiving ends are from different sources, clock synchronization, i.e. code synchronization, is required. I used an early-late gate to achieve code synchroniza
In the simple oscilloscope experiment in the previous article, when observing the waveform of the AC linear low-voltage power supply, what I saw was a regular undulating approximate straight line, ins
