Erasing A Sector That Isn't In .bin File Via Command-Line

jlefevre · May 28th 2024, 6:17pm

Chip: STM32H753VI
Flasher hardware: JLink Plus
JFlash version: v6.54 (for compatibility reasons)

.bin file writes from 0x08000000 to 0x0806C580

I can flash the chip successfully by calling J-Flash from the command line.

However, I need to wipe the sector at 0x080E0000 - 0x080FFFFF which is above the last address in the .bin file.

I have tried using -delrange0x080E0000,0x080FFFFF both by itself and with the project and bin files specified.
The command seems to be ignored by JFlash.

I did also try -erasechip, which would work, except that it takes too long to be done with each device we program in production.

My question is this: does -delrange only work for ranges specified in the data (.bin, .hex, etc.) file? If this is the case, should I have
my engineers create a data file that covers the appropriate range I need to delete? Is there another way to accomplish this besides
-erasechip?

Hello,

The -delrange command only affects the data file and not the chip itself.

To delete only a specific sector via the J-Flash command line application, follow these steps:

Select the sectors in the J-Flash GUI application (currently not possible via commands). J-Flash Flash Settings
Save the project.
Open the project via the J-Flash command line application with -openprj <FILENAME>.
Use the -erasesectors command.Only the previously selected sectors are erased.

For more details, please refer to the J-Flash Command Line Options.

Best regards,
Simon
