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 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....
Posted on January 30, 2013 at 23:01Hi all,I'd like to try uClinux on STM32F4, and I really like STM32F4DISCOVERY. I have two questions :1) Would it be possible to add an external RAM and FLASH chips somehow to this boar, via some free pads / ports t...
