I'm getting different assembly on my F28069 (non BIOS/DSP), depending on whether it's run in RAM or flash. If run in ram, the program counter goes off into the function in memory before it (due to the SB -47, NOV). The case in particular, I'm calling FindPosition with parameters passed by value, and initially in the function this happens:
008132: 9211 MOV AL, @0x11
008133: 0B60 DEC *-SP[32]
008134: 0536 ADD ACC, @0x36 << 16
008135: 6AD1 SB -47, NOV
008136: 0718 ADDL ACC, @0x18
008137: 9831 OR @0x31, AL
008138: 4CE0 TBIT *+XAR0[4], #0xc
008139: 775F NOP *-SP[31]
As opposed to running in flash:
3f1424: FE18 ADDB SP, #24
3f1425: E203024A MOV32 *-SP[10], R2H
3f1427: E2030148 MOV32 *-SP[8], R1H
3f1429: E2030046 MOV32 *-SP[6], R0H
3f142b: A844 MOVL *-SP[4], XAR4
Here's the two entries in the map for ram:
name origin length used unused attr fill
---------------------- -------- --------- -------- -------- ---- --------
PAGE 0:
RAML0 00008000 00000800 00000208 000005f8 RWIX
...
00008012 _CheckPosition1__8MotorSetFi12u_HallSensor
00008132 _FindPosition__5TableFfN21
The flash version runs with no problems. Any guidance?
