RRRRRR :)

i'm attempting to get the yunlea spi lcd with an hx8357 up

Sample code https://github.com/adafruit/Adafruit_HX8357_Library

Try with Arduino first maybe?

i decided to do a back-to-back SPI1 to SPI2 connection, to get familiar with SPI on the STM32F. that *alone* is proving tricky. and that's with just "simple wires" on a loopback arrangement.

the advantage of the loopback arrangement (and having a digital 72mhz scope) is i can see both ends of the conversation.

once i've got that, then i'll introduce the hardware. linux kernel has hx8357.c which is simpler (and GPL'd).
