Chung-Lin, thanks! i do have asm codes. after adding ".eabi_attribute 27, 3", nothing different. i am just a kernel engineer and an user to toolchain, i don't know too much well about toolchain like you. but i'll try to figure out more so that you can help. Anyway, thank you guys very much. > > > On 2011/4/28 06:06 PM, Barry Song wrote: >> Hi Andrew, >> >> 2011/4/28 Andrew Stubbs <andrew.stu...@linaro.org >> <mailto:andrew.stu...@linaro.org>>: >>> On 28/04/11 09:59, Barry Song wrote: >>>> >>>> my other two mails explain what happened, in fact link input file is >>>> simple: >>> >>> There must be more than one input file to the link, otherwise I >> believe you >>> wouldn't see this problem.
