Loading Large Quantity of STM32 Chips Simultaneously

[Kittywapus]

I'm working on a project that requires programming a large quantity of STM32 chips with the same code base. The chip is STM32L476RETx. While researching, I came across options like the STLINK-V3MODS and ST-LINK/V2, but they seem to support programming only one controller at a time.

Could anyone suggest alternative methods or tools that would allow me to program multiple STM32 chips simultaneously? I'm looking for efficient ways to streamline the programming process for a large batch of chips. Any insights or recommendations would be greatly appreciated. Thank you!

Hello @Kittywapus 

If you are looking for an industrial programming solution for more than one MCU on the same time. I suggest you to contact our local sales office. It may suggest you a few solutions.

Best Regards.

Boards or chips?

It is possible to use other STM32 parts to program via the AN3155 UART Protocol, AN2606 Boot Loader

Use NRESET, BOOT0 and a UART RX/TX.

You could make fixtures that scale, with RED/GREEN LEDs to indication completion or failure, and buttons to start.

You could perhaps make gang programmers that route SWD signals to successive devices.

The key word is "Gang" programming.

As others have noted, there are companies which offer this as a service.

Some distributors provide chip programming as a value-added solution. Although I'm not sure if PCBA are as keen holding onto pre-programmed stock as it complicates inventory.
