Hi all,
I am porting code from an existing Intel 8031 platform onto a STM32F4 The software performs PID calculations.
The softwqare has been running without issues on the 8031 for several years, but...

Hi all,
I am using the CAN interface on the STM3240G-EVAL for a CanOpen implementation.
All works fine up until the point where I need to transfer data via CanOpen PDOs which are more than 6 bytes in le...

Hi all,
When I build my application, the output .hex file indicates that the FLASH data footprint (.text) is 0xBB04, but according to the .map file it should only be 0xB How is this possible?
I am using th...
Posted on March 27, 2013 at 12:45Hi all,I am currently using the STM3240-EVAL kit. I am writing a custom bootloader which needs to store some configuration information in the FLASH memory at a specific address. I am however experiencing very odd beh...
Posted on February 05, 2013 at 13:50Hi all,I am having difficulty using an ST-Link V2 to program the FLASH of my STM32F103 on the STM3210E-EVAL board. It programs up until the last block and then states a message that programming to that location fa...
Posted on November 08, 2013 at 09:36Thanks for all the advice.I packed some structures bytewise in order to save space when storing the structure data to FLASH memory as part of configuration information. This caused all the unaligned access issues....
Posted on November 06, 2013 at 07:14The pointer points to address 0x10000271 and the contents of that address is 10.0.Some of the data passed to the function is located in the CCM memory area. I am going to investigate today whether this might be th...
Posted on November 05, 2013 at 15:23Thanks Clive,With of without byte packing it still fails.I will follow your advise and try to isolate the item giving problems. Although the array index is valid, I will add validation for safety sake.Will post ag...
Posted on November 05, 2013 at 14:53Hi Clive,You are right, that is bit 24. My mistake.I did pack the structure bytewise in an attempt to cancel out any alignment issues, but this had no effect.Any suggestions?Thanks,H
Posted on October 21, 2013 at 08:10Thanks Jack, that was exactly the problem. As you said, CANOpen does not support it by default. At this stage we don't need it, but at least I now know what is going on.The reason why I suspected a hardware problem...
