Hi FreeRTOS Forum Members:

Here is one problems that encountered during the usage of FreeRTOS-FAT-SL

I download the source codes from the official web stie and try to do the simple file operation in FreeRTOS system.

However, I have the following compiling errors, I think I do not have those definitions(such as gl_file,

glvolume,f_alloccluster........), so where I can find these definition files, does freeRTOS provided? Beacuse I can

not find on the google search engines !!

the Free RTOS Source Code File is from: https://github.com/jameswalmsley/FreeRTOS/tree/master/FreeRTOS-Plus/Source/FreeRTOS-Plus-FAT-SL

I'm afraid we cannot provide support for files or projects you have not obtained from us. If you are interested in FreeRTOS+FAT SL then we do have some pre-configured buildable examples in the main FreeRTOS download:

http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusFATSL/Demos/FileSystemWin32Simulator_demo.shtml

You might also be interested in the FreeRTOS+FAT (without the 'SL', and a completely different code base to the 'SL' product) pre-configured examples:
