Can't open PTF file

[Altera_Forum]

Hello all 

I have modified cpu cloclk to 100Mhz in SOPC Builder and cup input singal conneted from c1 of SDRAM PLL,then generate new ptf. But I could not open PTF file under uClinux-dist-test dir. <div class='quotetop'>QUOTE </div>  --- Quote Start ---  [faye@localhost uClinux-dist-test]$ make linux_hwselect SYSPTF=nios_clk100.ptf KCONFIG_NOTIMESTAMP=1 make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc-  ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- -C linux-2.6.x hwselect   no emulation specific options. make[1]: Entering directory `/home/faye/uClinux-dist-test/linux-2.6.x&#39;   RUNNING hwselect ERROR: Could not open SYSTEM ptf file. make[1]: Leaving directory `/home/faye/uClinux-dist-test/linux-2.6.x&#39;[/b]  --- Quote End ---    Do you know how to solve this problem ?  Thx !

Copy the ptf there, or give the absolute address of the ptf, something like SYSPTF=/home/faye/uClinux-dist-test/nios_clk100.ptf, or like hippo said, ~/project/nios_clk100.ptf.

Hi 

 I can run cpu freq up to 100Mhz on uClinux OS,and feel speed up to run algorithm program.  1.Make zImage in linux-2.6.16.1 dir  <div class='quotetop'>QUOTE </div>  --- Quote Start ---  # cat cpuinfo CPU:            NIOS2 MMU:            none FPU:            none Clocking:      100.0MHz BogoMips:      49.56 Calibration:    24780800 loops# free               total        used        free      shared      buffers   Mem:        7012        5292        1720            0            0# [/b]  --- Quote End ---    2.Make zImage in uClinux-dist-testdir (but i must add path ~/uClinux-dist-test to open my new ptf file).  <div class='quotetop'>QUOTE </div>  --- Quote Start ---  /> cd /proc /proc> cat cpuinfo CPU:            NIOS2 MMU:            none FPU:            none Clocking:      100.0MHz BogoMips:      49.56 Calibration:    24780800 loops /proc> free MemTotal:        6548 kB MemFree:          4844 kB Buffers:            0 kB /proc>[/b]  --- Quote End ---
