Problem after insert MicroSD

[Sergiv]

Hello In the picture the program. If I run it in debug mode (without MicroSD), the data from the GPS receiver are correct. If I insert MicroSD, the data from the GPS receiver and wrong are not complete, they can not handle. What could be the problem and how to solve the problem? Thank you. Lm3S8962

Hi Sergiv,

If the GPS is using the SSI port (which is also used by the MicroSD), that could cause this issue.  There is a similar conflict between the MicroSD and the OLED documented in the KnowledgeBase article linked below, and the workaround for that may be helpful for you.

GPS using UART1. I use C-code ''spi_init();'', but this did not help

Hi Sergiv,

Can you give me an example of the data you are logging when the MicroSD card is inserted?  How is it different from what you expect to see?

Also, I would like to figure out if the issue is with writing the data or reading it- you can do that by writing other data to a file (data that does not come from a serial read, the loop iteration count, for example) to see if that works as expected with the MicroSD inserted.
