Power supply parameters of Xilinx’ KC705 board, obtained via PMBus

What’s this? This is a dump of some parameters of the three power supplies on the KC705 board. More precisely, these are the outputs of the “getvals” utility, which is published on this post, running with the FPGA design published on this post. The control of these power supplies is discussed in another post of [...]

Example C sources for controlling a power supply with PMBus

Overview This post is best read after another post of mine, “Controlling the power supplies on a Xilinx KC705 FPGA board with PMBus“. This C code assumes that the FPGA is loaded with the design published in this post. These are the sources of utilities I wrote to fetch parameters and update the VADJ voltage [...]

FPGA source code for a PMBus master on Xilinx KC705

Introduction This post is best read after another post of mine, “Controlling the power supplies on a Xilinx KC705 FPGA board with PMBus“. C utilities for using the design outlined below can be found in another post of mine. These are the sources for allowing a computer to monitor and control the power supplies of [...]

Controlling the power supplies on a Xilinx KC705 FPGA board with PMBus

You probably don’t want to read all of this First of all: There is a GUI tool offered by TI to monitor and control its power controller. In hindsight, I have to admit it’s probably the quick & painless way to modify the voltage of a power rail (see last post on this page). I [...]

fetchmail, openssl and a sudden failure to authenticate certificates

Since around the beginning of December 2017, fetchmail stopped retrieving mails form Gmail servers silently, without issuing any kind of error message. Only when starting fetchmail in the foreground, I got fetchmail: Server certificate verification error: unable to get local issuer certificate fetchmail: This means that the root signing certificate (issued for /C=US/O=Google Trust Services/CN=Google [...]

The pin assignment of an FMC connector in CSV format

As the title says: These are the labels of an HPC (High Pin Count) FMC connector, in plain CSV format for easy handling. It was a bit odd to me that I didn’t find this info on the web myself. Just copy-paste: A1,GND A2,DP1_M2C_P A3,DP1_M2C_N A4,GND A5,GND A6,DP2_M2C_P A7,DP2_M2C_N A8,GND A9,GND A10,DP3_M2C_P A11,DP3_M2C_N A12,GND A13,GND [...]
