Part Number: AM3358
Other Parts Discussed in Thread: SYSBIOS
Tool/software: TI-RTOS
Good day,
I have taken the example program "NIMU_BasicExample_bbbAM335x_armExampleproject" and trimmed it down so I send myself a nice "hello" over TCP port 7 and it works great.
I have a separate program running that I am reading sensor data off of the SPI1 bus based on the "MCSPI_SlaveMode_MasterExample_bbbAM335x_armExampleProject" and that works great.
I am running into issues when trying to integrate what is working in my NIMU example into my SPI example.
I actually have the combined project compiling without warning or error and it downloads to by BBB. The issue is that when it tries to run, it says that it can't open the socket and the whole thing crashes. I have actually taken all of my networking code out of the program and the program still crashes.
Here is my working NIMU code for reference and what I tried to put in my SPI code:
