Hello,

i have designed a microblaze with EDK 12.2 and i tested a code C  of an mjpeg decoder:source files+ headers files

when i build the project i get this  list of errors&warnings

saharmjpeg/compute.c: In function ‘idctprocess’:

Done!

thank you in advance to give me an answer

‘XPAR_XPS_TFT_0_DEVICE_ID’ undeclared (first use in this function)

it seems that u did not include xparameters.h in set of header file of ur code if yes then look into xparametrs.h file in directory named "include" where ur program reside....check the proper TFT device id

regards

thank u it is resolved 

but i have other problems in ather codes!!!and i'm blocked 

in the split code of my mjpeg code i have so many errors related to the xilfatfs library !!and when i include it (software software platform setting i get other errors )

step1 (without the xilfatfs)

step2 when i added  the xilfatfs 

ERROR:EDK:3193 - 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:EDK:3414 - Error(s) while running DRCs.
make: *** [microblaze_0/lib/libxil.a] Error 2

i'm waiting for you to give a sollution ...

thank you in advance

step1 (without the xilfatfs)

The error u got in this step is mistakes in c programming where there could be some mismatch in ur function parameters.

"fetch.c:49: undefined reference to `sysace_fopen'" this sorts of error is common while u did not include Xilfatfs,u must have to include it from software paltform settings

at step 2

 "xilfatfs () - Sysace HW module not present or not accessible from this
processor. FATfs cannot be used without this module"

this seems that the processor has no access to Xilinx System ACE compact flash.As the XilFatfs filesystem access library provides read/write access to files stored on a Xilinx System ACE CompactFlash.now u have to use OPB SYSACE Interface Controller and pl2opb bridge to make it access via processor.

r u using xilkernel or standalone as ur os?
