Actually i had some problems accessing my packed structures without flows, I think that may help resolve things a bit. Eg with things like that:
cyg_uint8 i = 0; struct s_pelco_pattern_array a; a.command2_byte = i++; a.data3 = i++; a.data4 = i++; a.timestamp = i; I finish having a structure which looks like this in memory: cm2: 0x00 data3: 0x01 data4: 0x02 ts: 0x0300 Which is really not what i want to have eventually.
