Re: HDMI failure on Pi 3 B after overheating

That sounds like a defective board - 50 isn't all that hot - it can go to 85'C before it starts to throttle the CPU. Thanks jamesh. The point is that this board worked for an hour before it failed. Here I tend to believe that overheating caused the "damage" to the SoC. If so, should we all use a he...

I got my 3rd Raspberry Pi 3 B from Element14 in India and soon after I booted with Raspbian and within a few minutes, the HDMI display showed noise lines and finally the display totally failed. The Raspbian was working, as I could ssh into it. Subsequent reboots caused the HDMI to be blank, but syst...

Re: USB to Serial rs232 / rs485 problems

I am a beginner to Raspberry Pi and RS485. Could you give a simple C code to read data from a RS485 slave using FTDI RS485 cable. Which Driver should I use for Raspberry Pi?
Thanks

Re: BerryTerminal (Edubuntu/LTSP terminal)

@Max I tried the version 20120602 and created a SD Card, but could not get the contents of the partition 2. It gave wrong fs type. But the partition 1 is visible with all the files. So I tried mounting as loop. That also gave the same error as shown. Can you point out the mistake I am making? sudo m...
