How to Access CompactFlash by using SystemACE?

Hi Guys,



I was trying to access CF by using API sysace_fread and sysace_fwrite. I checked xilfatfs library in the software platform settings and #include , but edk still complains.


---------------------------------------------------------------------------= =AD-------------------------------------------- Running DRCs for OSes, Drivers and Libraries ... ERROR:MDT - issued from TCL procedure "::sw_xilfatfs_v1_00_a::xilfatfs_drc" line 15 xilfatfs () - Sysace HW module not present or not accessible from this processor. FATfs cannot be used without this module


ERROR:MDT - Error while running DRC for processor ppc405_1...


make: *** [ppc405_0/lib/libxil.a] Error 2



---------------------------------------------------------------------------= =AD--------------------------------------------


Has anyone experienced this before? Any input would be appreciated!


Thanks in advance,


Yao

Do you have the system ace module accessible over the bus from your processor?

Hi Jon,

The previous problem was solved. I was supposed to use ppc405_0, not ppc405_1. I think thats why edk complains. A silly mistake.

But, I run into another weird erorr. sysace_fwrite() cannot be found.

--------------------------------------------------------------------------- undefined reference to `sysace_fwrite' collect2: ld returned 1 exit status make: *** [CF_demo/executable.elf] Error 1

---------------------------------------------------------------------------

Xilfatfs lib is chosen and included in the main.c, as follow. If I comment out sysace_fwrite, no errors come up during compilation. How come can edk only find sysace_fread but sysace_fwrite? Any input would be appreciated!

Thanks in advance,

Yao
