Hi, Thanks Pavel, Xiao and especially Luis for their quick reply. So as suggested, I'll firstly try to build the latest compat-wireless driver with the 2.6.25 kernel. And update the kernel to 2.6.34 as the last attempt which requires support from Freescale. Let me briefly mention a little background and the problem I've encountered when building the driver. Our project is base on a Freescale MPC8377EWLAN reference design which runs by a MPC8377 PowerQUICC II PowerPC processor. It uses LTIB to develop and deploy BSP for this architecture and the Linux kernel version provided is 2.6.25 (a slightly patched kernel to adapt the processor) The wireless interface we're using is Wistron DNMA-83 (equivalent to Unex DNMA-83) which uses Atheros AR9160 chipset. To fully utilize the 802.11 a/b/g/n mode provided by the chipset (and the proprietary driver came with the package has too many problems), we look for the ath9k driver and would like to build it with the 2.6.25 kernel. So what I did to build the driver is to provide the KLIB and KLIB_BUILD with the path of 2.6.25 source and modified the CROSS_COMPILE variable in the .config of the kernel to make sure it uses the MPC8377 toolchain to compile the source. However, the following error occurred (With my latest trial of the bleeding edge compat-wireless-2.6): make -C /MyProject/ltib-mpc8377ewlan-20090922/rpm/BUILD/linux-2.6.25 M=/root/Desktop/compat-wireless-2009-12-11 modules make[1]: Entering directory `/MyProject/ltib-mpc8377ewlan-20090922/rpm/BUILD/linux-2.6.25' CC [M] /root/Desktop/compat-wireless-2009-12-11/drivers/misc/eeprom/eeprom_93cx6.o cc1: error: unrecognized command line option "-mno-red-zone" cc1: error: unrecognized command line option "-mcmodel=kernel" cc1: error: unrecognized command line option "-maccumulate-outgoing-args" /root/Desktop/compat-wireless-2009-12-11/drivers/misc/eeprom/eeprom_93cx6.c:1: error: -m64 not supported in this configuration make[3]: *** [/root/Desktop/compat-wireless-2009-12-11/drivers/misc/eeprom/eeprom_93cx6.o] Error 1 make[2]: *** [/root/Desktop/compat-wireless-2009-12-11/drivers/misc/eeprom] Error 2 make[1]: *** [_module_/root/Desktop/compat-wireless-2009-12-11] Error 2 make[1]: Leaving directory `/MyProject/ltib-mpc8377ewlan-20090922/rpm/BUILD/linux-2.6.25' make: *** [modules] Error 2 I'm a newbie in linux development especially for embedded linux, so please forgive me if any question I asked are too stupid or wrong in concept. Thanks again for generous help from all you guys.
