RL-ARM: FLASH FILE SYSTEM LINKER ERROR
Information in this article applies to:
- RL-ARM Version 3.21 Flash File System
QUESTION
I am using the RL-ARM SD/MMC flash file system in my application and after installing the new RL-ARM version I get the linker error:
Error: L6218E: Undefined symbol _MC_CSIZE (referred from fs_fat.o) Error: L6218E: Undefined symbol mc_cache (referred from fs_fat.o)
What causes the linker error and how can I solve the problem?
ANSWER
The flash file system in RL-ARM version 3.21 supports SD/MMC file caching to increase the speed of file write and file read. An updated library is provided. To avoid the linker errors you need to use the new version of file File_Config.c. The file can be found in folder ..\Keil\ARM\RL\FlashFS\SRC.
MORE INFORMATION
- Refer to RL-FlashFS in the RL-ARM User's Guide.
