There can only be 5 sessions open total, with 1 per service. When there's already a session open for the target service(with session_count<5), SPI-module will wait for the original thread to terminate(triggered by the session closing), then start a new thread.

SPI Services[edit]

  • "SPI::NOR" (used by cfg:NOR)
  • "SPI::CD2" (used by Codec Services)
  • "SPI::CS2"
  • "SPI::CS3"
  • "SPI::DEF"

There can only be 5 sessions open total, with 1 per service. When there's already a session open for the target service(with session_count<5), SPI-module will wait for the original thread to terminate(triggered by the session closing), then start a new thread.

SPI Service Commands[edit]
