STM32 L476RG only 32 KB for upload

[github-rkaiser]

After successfully compiling my STM32 L476RG program with the Visual Micro Extension for the Arduino IDE

Program STM32-L476RG size: 21352 bytes (used 2% of a 1048576 byte maximum) (2,00 secs)
Minimum Memory Usage: 1420 bytes (1% of a 98304 byte maximum)

I get the message

Uploading 'STM32-L476RG' to 'Nucleo-64 (STMicroelectronics_Nucleo_64)' using 'COM10'
Uploader started for board Nucleo-64 (STMicroelectronics_Nucleo_64)
Upload method will be: bootloader
Uploading via Bootloader
ls\2.2.1\win\massStorageCopy.bat -I o_64\Release/STM32-L476RG.ino.bin" -O "NODE_L476RG"
Nicht genügend Speicherplatz auf dem Datenträger im aktuellen Laufwerk.
Nicht genügend Speicherplatz auf dem Datenträger im aktuellen Laufwerk.

The uploader returned an error

This sounds strange since the L476RG has capacity of 1 MB.

In the windows filesystem there is a drive NOD_L476RG with a capacity of 32 KB.

What do I have to do to upload a program to this board?

Thanks Richard

Hi @github-rkaiser Try to update the stlink firmware of your board.

Hi @github-rkaiser I've tested and it works. This issue is linked to the STLink firmware which handle the mass storage feature. So as stated you have to update the STLink firmware of the board using the STM32CubeProgrammer. Blue button "Firmware upgrade"

I close this issue as it is not related to an issue with the core.
