Posted on January 24, 2013 at 07:53I've noticed that STM32L initializes Flash to 00 instead of FF. Yes, it has an EEPROM section that can be used for 4KB of NV data storage, which is great. I suspect that is actually NOR Flash as well.Anyway, if S...
Posted on January 31, 2013 at 13:38 Hi, I have a problem for the second time, I don't know why but hardware breakpoint, sometimes, still in stm and I can't delete it. I use OpenOCD 0.6.1 and gdb This is my gdb log : ...
Posted on January 31, 2013 at 13:06Trying to get a linux toolchain up and running to eventually program an STM32L Discovery board. I have Code Sourcery CodeBench Lite set up in a folder and a Make script set up to build it all. Right now it's just...
Posted on January 31, 2013 at 13:48Hi all,Is it possible to read out protect only one specific area of flash?I want to use a bootloader that can program both encrypted and un-encrypted programs.I need to protect the bootloader from being read so un-...
Posted on October 12, 2012 at 11:28Hey there, I am pretty new to micrcontrollers and such. I recently bought a STM32VL Discovery, which I am programming with CoCoox IDE. My goal is to read out the start-up values of internal RAM. By start-up values ...
Posted on September 05, 2012 at 04:38Hi All, I had the DAC working using DMA to out put a sinewave continuously and it seems to have stopped working when I tried to change which timer I triggered off. After changing the timer configuration back it s...

Posted on January 24, 2013 at 14:48Hi all,My TIM3 timer is setup to run at 10Khz which it does when i compile with -O0.When i compile with -03 or -Os, the timer speed increases to 20khz.All other build configs (gcc, linker, libs, etc) stay the same....
