Hello,
I am trying to save data on an microSD card using SPI1. I am following the firmware in this discussion Working NRF9160 SD Card Example on SDK 1.9.0. In addition I have another peripheral on SPI0 bus which is working correctly. Disk initialization do not work (I am using basically the same code as the link) and returns error code of '-5'. I experimented a bit with the configurations and either I am getting an error code of -5 or the main function resets.
When
&spi1 {
compatible = "nordic,nrf-spim";
.
.
.
}
I get rebooted back to the main function.
When
&spi1 {
compatible = "nordic,nrf-spi";
.
.
.
}
I get error code of -5
I researched the forum and found lots of topic about SPI SDHC interfacing issues, yet, they did not solve my problem. I tried changing pins since -5 seems to be EIO code ( disk program files return -EIO etc.) but not sure of that actually represents 'EIO' error code. It also might be FR_NO_PATH
Here is the debugging output,

EDIT1:
I have traced the stacks just before the systes reboots back to the main function, its 'z_impl_spi_transceive()' function. Here is the stack call-list,
