Hello

 

I wanted to use the sd card function of RT1052, but found that mimxrt1052xxxxx_flexspi_nor_sdram.icf was not used in the example.When using mimxrt1052xxxxx_flexspi_nor. icf, the sd card can work normally, but when using mimxrt1052xxxxx_flexspi_nor. icf, the sd card cannot work.

 

Below is the print information using mimxrt1052xxxxx_flexspi_nor.icf
