U-boot for NIOS-II Cyclone-II​I (EP3C40F78​0I7)- compilation error

[Altera_Forum]

Hi , 

 I need to port the U-boot (1.3.3) to NIOS-II Cyclone-III (EP3C40F780I7) based customized board. Started following the Altera wiki http://www.alterawiki.com/wiki/dasuboot instructions.   1) Generated the my_nios2_fpga.h from sopc file. 2) Copied the relevant nios2_generic files. 3) Used the installed tool chain " nios2-linux-uclibc-" for compilation. 4) Using U-buntu linux distribution for u-boot compilation.   Following compilation errors are coming during U-boot compilation:   u-boot-1.3.3$ make clean u-boot-1.3.3$ export CROSS_COMPILE=/opt/nios2/bin/nios2-linux-uclibc- u-boot-1.3.3$ make my_nios2_config Configuring for my_nios2 board... u-boot-1.3.3$ make Generating include/autoconf.mk.dep for dir in tools examples api_examples ; do make -C $dir _depend ; done make[1]: Entering directory `/home/borelas/u-boot-1.3.3/tools' make[1]: Nothing to be done for `_depend'. make[1]: Leaving directory `/home/borelas/u-boot-1.3.3/tools' make[1]: Entering directory `/home/borelas/u-boot-1.3.3/examples' make[1]: Nothing to be done for `_depend'. make[1]: Leaving directory `/home/borelas/u-boot-1.3.3/examples' make[1]: Entering directory `/home/borelas/u-boot-1.3.3/api_examples' make[1]: Nothing to be done for `_depend'. make[1]: Leaving directory `/home/borelas/u-boot-1.3.3/api_examples' Generating include/autoconf.mk make -C tools all make[1]: Entering directory `/home/borelas/u-boot-1.3.3/tools' gcc -Wall -pedantic -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o img2srec.o img2srec.c gcc -Wall -pedantic -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -o img2srec img2srec.o strip img2srec gcc -g -Wall -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o mkimage.o mkimage.c gcc -g -Wall -pedantic -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o crc32.o crc32.c gcc -g -Wall -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o image.o image.c gcc -g -Wall -pedantic -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o md5.o md5.c gcc -g -Wall -pedantic -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o sha1.o sha1.c gcc -g -Wall -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o fdt.o fdt.c gcc -g -Wall -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o fdt_ro.o fdt_ro.c gcc -g -Wall -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o fdt_rw.o fdt_rw.c gcc -g -Wall -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o fdt_strerror.o fdt_strerror.c gcc -g -Wall -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o fdt_wip.o fdt_wip.c gcc -Wall -pedantic -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -o mkimage mkimage.o crc32.o image.o md5.o sha1.o fdt.o fdt_ro.o fdt_rw.o fdt_strerror.o fdt_wip.o strip mkimage gcc -g -Wall -pedantic -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -O -c -o envcrc.o envcrc.c gcc -g -idirafter /home/borelas/u-boot-1.3.3/include -idirafter /home/borelas/u-boot-1.3.3/include2 -idirafter /home/borelas/u-boot-1.3.3/include -DTEXT_BASE= -DUSE_HOSTCC -c -o environment.o environment.c In file included from environment.c:32: /home/borelas/u-boot-1.3.3/include/environment.h:107: error: ‘CFG_ENV_SIZE’ undeclared here (not in a function) make[1]: *** [environment.o] Error 1 make[1]: Leaving directory `/home/borelas/u-boot-1.3.3/tools' make: *** [tools] Error 2     Any inputs to resolve these error?  Thanks, Siva

Hi, 

 U-boot 1.3.3 does not have nios2-generic approach. Starting from U-boot V2010.12 , it supports the nios2-generic approach. with this I could able to compile and download the U-boot.   Still i have some issues with ethernet. Post more once i will resolve.   Thanks, Siva
