Yes, this looks OK. > But I get an error code (2) on my M0 board. > >FT_New_Memory_Face: 2 The error codes are given in file `fterrdef.h'; errorĀ 2 means `unknown file format'. Maybe an endianness problem while setting up the external array holding the PCF data? If you activate debugging with #define FT_DEBUG_LEVEL_ERROR #define FT_DEBUG_LEVEL_TRACE in `ftoption.h', then setting the environment variable `FT2_DEBUG' to `any:7' you will perhaps get more detailed information on the problem FreeType has encountered. [In case your environment doesn't have environment variables you have to adjust `ftdebug.c' accordingly.] Of course there could also be a bug in FreeType. However, I can't debug this... > By the way, the assembly code is broken with thumb2: > > static __inline FT_Int32 > > FT_MulFix_arm( FT_Int32 a, > > FT_Int32 b ) > > { > > FT_Int32 t, t2; > > > > > > __asm > > { > > smull t2, t, b, a /* (lo=t2,hi=t) = a*b */ > > mov a, t, asr #31 /* a = (hi >> 31) */ > > add a, a, #0x8000 /* a += 0x8000 */ > > adds t2, t2, a /* t2 += a */ > > adc t, t, #0 /* t += carry */ > > mov a, t2, lsr #16 /* a = t2 >> 16 */ > > orr a, a, t, lsl #16 /* a |= t << 16 */ > > } > > return a; > > } Can you fix it? I have zero knowledge w.r.t. assembler code.
