Cannot get correct data from MAX31865 SPI bus

[LMI2]

Has anybody worked with MAX31865 PT100 sensor chip. I have a module with that chip on a STM32F746 board and SPI bus gives me only zeros. Local loop MOSI->MISO works. The chip doesn't look very complicated but I get nothing out off it. The module has worked on an Arduino board some time ago.

Have you find a solution for this? I am facing samep problem with a STM32F769

Yes, I have. I sent two kinds of solutions here in a post some time ago. I recommend a logic analyzer, I used DreamsourceLab LA.

Also, take care of pull up/down resistors. I don't remember exactly but I would recommend to put every SPI pin should have one.
