SPI ports P0_4, P0_5, P0_6, P0_7 wrong?
According to the MAX32625PICO MBED page, the SPIM0 is located at P0_4 for CLK, P0_5 for MOSI, P0_6 for MISO and P0_7 for SSEL. But in the MAX32625PICO datasheet on page 4/5 is given in table 3: P0_6 = SSEL, P0_5 = MISO, P0_4 = MOSI and P0_7 = SCLK. What is now correct? The same pin assignment as in the datasheet is also on the MAX2771EVKIT, for which I want to program the MAX32625PICO (which is placed on the evaluation kit). I found, that if I take the assignment according to datasheet from Maxim, the board will blink red because the assignment is considered to be invalid. In the file PeripheralPins.c (in TARGET_Maxim/TARGET_MAX32625), this assignemnt is listed in lines 109 following and after changing it there, I was able to operate without the red led blinking (which shows a runtime error according to Mbed doc). Now I would like to know which is the correct assignment and if there are other places in Mbed/target source code where I have to change the pin assignment, because I cannot see any output for the SCLK or SDATA in both pin assignment cases with an osi. Thank you!

If my understanding is not correct, please let me know. You are building MAX32625 image and run it on MAX2771EVKIT. I checked their datasheet, they are using different chip so I don't think the image will work properly.
