Hello Ted,
I have tried the patch. With the AT90S8515 I get the following output:
# ./uisp -dprog=stk500 -dpart=AT90S8515 --rd_fuses -v -mode=s
Atmel AVR AT90S8515 is found.
Cannot read low fuse bits on this device.Fuse Low Byte = 0xff
Cannot read high fuse bits on this device. Fuse High Byte = 0xff
Cannot read extended fuse bits on this device. Fuse Extended Byte = 0xff
Cannot read calibration byte on this device. Calibration Byte = 0xff --
Read Only
ReadLockBits failed: are you sure this device has lock bits?
# ./uisp -dprog=stk500 -dpart=AT90S8515 -v -mode=s --raref
Atmel AVR AT90S8515 is found.
ARef is set to 5.1 V
#./uisp -dprog=stk500 -dpart=AT90S8515 -v -mode=s --rvtar
Atmel AVR AT90S8515 is found.
VTar is set to 5.1 V
Now I have changed to AT90S8535:
# ./uisp -dprog=stk500 -dpart=AT90S8535 --rd_fuses -v -mode=s
Atmel AVR AT90S8535 is found.
Cannot read low fuse bits on this device.Fuse Low Byte = 0xff
Cannot read high fuse bits on this device. Fuse High Byte = 0xff
Cannot read extended fuse bits on this device. Fuse Extended Byte = 0xff
Cannot read calibration byte on this device. Calibration Byte = 0xff --
Read Only
Found Lock bits here as 0
after that lock bits are fc
Lock Bits = 0xfc
BLB12 -> 1
BLB11 -> 1
BLB02 -> 1
BLB01 -> 1
LB2 -> 0
LB1 -> 0
This I don't understand. What is the meaning of -dpart parameter?
# ./uisp -dprog=stk500 -dpart=AT90S8515 -v -mode=s --raref
Atmel AVR AT90S8535 is found.
ARef is set to 5.1 V
Regards,
Robert
PS: If I should do dome more tests, please let me know and give me detailed
advice. My hardware is limited to STK500, AT90S8515, AT90S8535 and ATmega163.
