HW SPI Freezes when changing host controller #67

Closed MrSurly closed 6 years ago

MrSurly commented 7 years ago

Just putting this here to document an open issue in the IDF that affects HW SPI: spi_device_transmit doesn't return when changing host ID.

Interested in this issue as I often have multiple SPI devices on the bus with different SPI modes (and sometimes clock speeds). If it is an IDF issue there will be no fix here for a bit.

Evidently, this has been fixed "some time ago," per Espressif.
