I just got firmware downloaded on STM32F303 start but have not yet tested anything. Oddly enough in SystemWorkbench from ST Microelectronics I had to use manual load command "monitor flash write_image erase DieBieSlave-Firmware.elf" and run openocd separately. This is not the case on another card with same Micro controller I have. I am thinking a little bit of the copyright issue since there are no license anywhere. I found two malloc I have removed so now there should be no memory allocation on the heap. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
