How to program through Raspberry Pi 3


I want to program through Beaglebone, is it possible? we have 12 PCBA in a single panel, each PCBA have Z-Wave and STM8 MCU
For the Z-Wave SPI interface is available for programming and for STM8 SWIM (Single Wire Interface Module) is available for programming

So, we need to do parallel programming to all PCBA’s at the same time through the RPi, is it possible? if yes then how? Kindly do the needful for the same
