Migrated from Debian 32bit to 64bit through dual boot

May 16, 2016

The desktop where I do most of my stuff is a Debian testing 32bit. Recently Google Chrome team declared the end of support of 32bit Linux distributions, and I decided to take the occasion to migrate towards a 64bit Debian. I read some guides around, some old, some with big warnings and disclaimers, some interesting. Ultimately I […]

My mother has an Acer Aspire One 522 netbook (as for the post title) and used it to surf the net and play some Facebook games… until it fell hard while it was on, and it wouldn’t boot any more: it would get stuck on the boot screen where you can tap F2 to enter […]

This week I bought a Sapphire R7 240 2GB DDR3 graphic card, sporting an AMD Radeon R7 240 chip suggested by Tom’s Hardware march wrap-up.  I changed card because my old XFX GeForce 7300 GS had a broken fan and it was time to let it go (before the hot summer). My desktop PC has a Debian testing installation, […]

STM32-P152 development with Eclipse on Linux

February 23, 2014

In this post I show how to use Eclipse to create a simple "blink" program, flash it on a STM32-P152 board and attach to it with a debugger. This has been executed with the help of Eclipse plugins, GCC ARM Embedded toolchain, OpenOCD, C232HM FTDI JTAG cable. This approach can be adapted to many Cortex-M targets and many JTAG adapters.
