Posted on August 25, 2015 at 03:34Can the program image generated by MDK be loaded/written directly into STM32F4 flash using ST-Link Utility, without using MDK to orchestrate the load by ST-Link Utility ?
Posted on August 22, 2015 at 04:11Is there a document that describes the selection of push pull, open drain, maximum output speed, AHB clock, etc for GPIO port operation on STM32F427xx under STM32CubeMX ? The datasheets for the chips on the PCB t...
Posted on July 26, 2015 at 21:49In a STM32F427/DP83848 PCB configuration, I am finding that the LWIP/Ethernet initialization is hanging at a statement waiting for the Software Reset to clear. What specifically is the Ethernet MAC engine awaiting ? I...
Posted on August 25, 2015 at 23:25After experimenting with the different GPIO configuration options, I did not notice much difference in output voltage measurements. In all cases, I am seeing all of my data pins transition between 3.3V and maybe 3V...
Posted on August 22, 2015 at 23:25That document section referenced does not describe what the STM32 circuitry is doing differently under each choice and under which circumstances, connected to what sorts of devices, each choice of GPIO configuration...
Posted on July 26, 2015 at 23:28I do not have a post-able schematic. However, I am looking for raw information about what causes a failure to exit Software Reset of the Ethernet unit in the STM32F427 . For instance, I am in the process of re-config...
