Not enough memory at STM32 L476RG

After successfully compiling my  STM32 L476RG program

Code (C++)
Select All
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
Code (C++)
Select All
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

Thanks for the report.

Checking on a similar board (F103RB) it shows the "NODE_F103RB" partition when it is viewing the onboard STLINK Probe.  When the jumpers are correctly configured I then see a 136KB Partition for the normal Mass Storage Upload.

If you add two jumpers to the CN2 header (which is labelled as STLINK when open, and NUCLEO when closed) you should then see the correct partition for upload via Mass Storage.

See Page 13 of the ST Manual: https://www.st.com/resource/en/user_manual/um1724-stm32-nucleo64-boards-mb1136-s...

Hi Simon,

thanks for your reply.

The two CN2 jumpers were set as you suggested. I removed them, but this had no effect on the size of mass storage device. It is still 32 KB.

Please help.

Thanks 
Richard

The STLink jumpers will need to be present to allow the mass storage upload (Or STLink v2.1 + OpenOCD (vMicro) Upload), and the device also needs to be disconnected and reconnected to the PC to repower it for this to take effect.

Do you have any other jumpers set on your board?

The only jumpers that are set beside the STLink-jumpers are CN11, CN12, IDD and C20.

Regards
Richard

They all sound correct to our knowledge, it may be best to ask the question to the board package creator on GitHub:
https://github.com/stm32duino/Arduino_Core_STM32

I assume you have the same experience in the Arduino IDE?
