Error In spi DMA interfacing with SD card

Hello,

I would like to implement SPi interface using DMA to my SDfile System for STM32l0 Board. I got to see an example program for test and started working on it with little changes. I am getting some linker error during execution.

  • List Item 1 :Error: L6218E: Undefined symbol spi_dma_get_info (referred from spi_dma_common.o).
  • List Item 2:Error: L6218E: Undefined symbol spi_dma_handle_setup (referred from spi_dma_common.o).
  • List Item 3:Error: L6218E: Undefined symbol spi_dma_irq_setup (referred from spi_dma_common.o).

I am unable to find the error and could any one please provide me suggestions for this kind of linker error.

Hi,
If you are using my library,
SDFileSystemDMA
https://developer.mbed.org/users/mimi3/code/SDFileSystemDMA
( Test program is SDFileSystemDMA-test.)
I will investigate the issue.

I've fixed the issue and update library so if you update
"SDFileSystemDMA-test" project,compilation should be ok.
