Flashing multiple STM32G474s with Segger J-Link

[PC999]

Hello,

I'm trying to build a flexible system where each system "channel" will have its own micro (probably an STM32G474 or similar).  Each micro will run the same code but I'd really like to link them together so they're all programmed from one header in (as far as a production technician is concerned) one operation from blank devices.

I believe JTAG can daisy-chain multiple devices - has anyone got experience of doing this with a Segger J-Link please?

Thanks a lot - Paul.

Probably the best place to find such people would be the Segger J-Link forum:
