Hi, >> Have you got this error on the real SH2A-FPU hardware? Yes, we got this error on SH72513(SH2A) hardware. When the same code is run on simulator, the "address error" occurs on encountering the "fmov.d" instruction.
>> couldn't find any description for 8-byte alignment restriction for >> double data on memory in my SH2A manual Please refer the section 3.3 "address errors" in the SH2A software manual at the following link:- http://documentation.renesas.com/eng/products/mpumcu/rej09b0051_sh2a.pdf It is mentioned that "Double longword data accessed from other than double longword boundary" results in address error.
