Re: [Uisp-dev] fuses and lock bits

[Theodore A. Roth]

Currently uisp can not handle reading/writing of fuses to devices which do
not allow SPI access to the fuses. The 8515, sadly, falls into this
category.

Can you try the snapshot and accompanying patch from this url?

http://savannah.nongnu.org/download/uisp/snapshots/

I'd like to have data points for various devices with respect to the patch
before I merge it into cvs.

:) Hello,

:) maybe some one of you can give me a hint. I am trying to read out the fuses
:) and lock bits. The command is as follows:
:) uisp -dprog=stk500 -dpart=AT90S8515 --rd_fuses -v=3
:)
:) I am getting the following output:
:)
:) Vendor Code: 0x1e
:) Part Family: 0x93
:) Part Number: 0x01
:) Atmel AVR AT90S8515 is found.
:) Page Write Disabled
:) FLASH Write Delay (t_wd_flash): 11111 us

:) Cannot read low fuse bits on this device. Returning 0xff
:) Fuse Low Byte      = 0xff

:) Cannot read calibration byte on this device. Returning 0xff

:) Am I doing something wrong? STK500 has version 1.10.

:) Thank you in advance.

:) PS: ist there anywhere a description of these parameters (range,default ...)?
:) -dt_sck      Set minimum SCK high/low time in micro-seconds (default 5)
:) -dt_wd_flash Set FLASH maximum write delay time in micro-seconds
:) -dt_wd_eeprom Set EEPROM maximum write delay time in micro-seconds
:) -dt_reset    Set reset inactive (high) time in micro-seconds
