It seems(!) that the device is programmed correctly, but I want to be sure.
#Ihex vs hex verification#
But when I try to program the device, I got verification error. I already managed to get the settings into the. elf/.hex file, so our manufacturing department only needs to download this file. My goal is to provide the option bytes directly in the. If it is not programmed (the STM32 is empty, virgin or the program was not made to load the BIN file), it will be necessary to use St-Link or another programmer, or perhaps making use of the DFU method described in the tutorial above (DFU - DfuSe).I'm using latest STMCubeProgrammer/ST-Link-Utility releases. To use the *.BIN file it is necessary that the STM32 is already programmed to load the BIN file. It sounds a little confusing, but we have these steps:ġ- The STM32CubeIDE generates the *.elf file.Ģ- After compilation, the *.elf file is converted to *.hex.ģ- CRC value is added in *.hex file via srec_cat application.Ĥ- Now the *.hex file is converted to *.bin.ĥ- The BIN file is then stored on a USB flash drive.Ħ- STM32 updates firmware using USB flash drive file. Objcopy -input-target=ihex -output-target=binary code00.hex code00.bin

S19 file, for do thisīut it seems that using the *.DFU file is not as standalone as using the *.BIN file, so I found this other code that converts the HEX file (generated with CRC) to the *.BIN file, which can be used with a USB stick, as per the tutorial cited at the beginning of this answer (11.3 USB MSC DFU host): This need to use a HEX file facilitates the operation of the implementation of the ROM.hex file generated with the CRC value, being practically a continuity:
#Ihex vs hex upgrade#
Upgrade the STM32 firmware during development or pre-production. The ability to programĪn "empty" STM32 device in a newly-assembled board via USB. JTAG, ST-LINK or USB-to-UART cable are needed.
The key benefits of the DFU Boatloader are: No specific tools such us This other tutorial deals with using the file with *.DFU extension:
#Ihex vs hex how to#
Note: In this case, the file to be written is ROM.hex (you will need to configure the STM32CubeIDE to be able to do this operation, the IDE uses the *.elf file, see how to do it in the tips above) \checksum.batĬontents of the checksum.bat file: #!/bin/bash Unfortunately the amount of code is too big to post here directly, but I leave the code related to the other answer below:Īrm-none-eabi-objcopy -O ihex "$.hex" &. Some tips and solutions about this CRC usage (Windows/Linux) To simplify the process, please put srec_cat.exe into the root Srec_cat could be used to generate CRC checksum and put it into HEXįile. The binary file (*.bin) can be obtained with the help of the command that the colleague above explained (Employed Russian), and it (command) can also be adapted to produce a file containing the comparison value for CRC usage, as can be seen some details in these following posts: Notes: The example code from the STM32 tutorials are available in the descriptions of the videos themselves.
#Ihex vs hex series#
This tutorial is part of a series of videos that are highly recommended for the programmer to watch, to understand a little better how the STM32 USB ports work and use (videos provided by the STM32 manufacturer itself, I recommend that the programmer watch all the videos on this channel): STM32 USB training - 11.3 USB MSC DFU host labs In case someone wants to use the DFU ("Do a Firmware Upgrade") function, this tutorial teaches how to use the binary file to be loaded via USB, when the STM32 is operating with USB Host (or maybe OTG): It certainly doesn't find instructions to blink the lights. When it finds "garbage" it doesn't understand, it probably just halts. Run arm-none-eabi-readelf -h tim_time_base.elf to see what some of this metadata are.īut when you processor jumps to location 0x8000000 after reset, it is expecting to find executable instructions, not metadata. The tim_time_base.elf is an ELF file - it has metadata associated with it. Question 2: Flashing the bin file gives the expected result (Leds blinking) However the leds are not blinking by flashing the elf file $(STLINK)/st-flash write $(PROJ_NAME).elf 0x8000000 so why? The actual command that runs is arm-none-eabi-objcopy -O binary tim_time_base.elf tim_time_base.bin When make executes this command: $(OBJCOPY) -O binary $(PROJ_NAME).elf $(PROJ_NAME).bin It assigns value arm-none-eabi-objcopy to make variable OBJCOPY. I opened the man but I didn't fully undrestand can anyone explain it simply ? Question 1: What does OBJCOPY=arm-none-eabi-objcopy in this case.
