Fatal Bug: STM32CubeProgrammer 2.4.0 CLI, Upload size is bigger than flash memory size

[eGDY2CVw4jwV]

Hi,

when I'm trying to read the content of the internal flash memory via internal UART DFU bootloader STM32CubeProgrammer 2.4.0 CLI reports the following fatal error: 

> .\bin\STM32_Programmer_CLI.exe -c port=COM3 br=57600 P=EVEN db=8 sb=1 -u 0x8000000 0x400 test.hex

Serial Port COM3 is successfully opened.
Port configuration: parity = even, baudrate = 57600, data-bit = 8,

Activating device: OK
Chip ID: 0x410 
BootLoader protocol version: 2.2
Device name : STM32F101/F102/F103 Medium-density
Flash size : 128 KBytes (default)
Device type : MCU
Device CPU : Cortex-M3
 
 
UPLOADING ...
 File : test.hex
 Size : 1024 Bytes
 Address: : 0x8000000
Read progress:
Error: Upload size is bigger than flash memory size.

This happens for all sizes, except 0 Bytes.

Using the STM32CubeProgrammer GUI works as expected.

I tried with a STM32F103C8T6 and a STM32F407VGT.

My system: 

• Windows 10 1903 x64
• STM32CubeProgrammer 2.4.0 CLI

Best regards!

Hi @SBros.1​ 

Please try with the last STM32CubeProgrammer version 2.5.0, then tell me if it solve the issue or not.

Hi Nesrine

Thank you for your reply! With the new version 2.5.0 is does work.

(e.g. STM32_Programmer_CLI.exe -c port=COM5 -r 0x8000000 4096 read.hex)

Kind regards,
