Posted on October 22, 2013 at 02:09In the STM32F205 datasheet, it says that in STOP power mode, all clocks on the 1.2V power domain are stopped. Is there anywhere I can look to see which clocks are part of the ''1.2V power domain'' ? Particularly, I...

Posted on March 22, 2013 at 00:42I am holding an STM32F205 in reset (NRST pin low). I am measuring the current into VDD1-4 plus AVDD at 1.7mA. I am using 3.3V. 0.1mA I can explain through the pull-up resistor on the NRST pin per datasheet. 0.3mA I [...

Posted on February 28, 2013 at 22:55I am getting a Hard Fault in FLASH_ReadAccess64Cmd(ENABLE). The line is FLASH->ACR |= FLASH_ACR_ACC64; When I cold boot, it seems to work fine, but if I reset in the debugger it can't seem to get by this function....
