help writing to AT90S2313 with uisp via AVR-PG1B ?

Development Boards MicroMod

has anyone had any luck doing this? i can read the flash and eeprom and fuses via this command:

$ uisp -dprog=dasa2 -dserial=/dev/ttyS0 --download --segment=flash --rd_fuses

when i try to write, it looks like it succeeds, but then a subsequent read still shows all 'FF’s

my write command looks like this:

$ uisp -dprog=dasa2 -dserial=/dev/ttyS0 --upload if=test.hex --segment=flash -v=3 -dno-poll

which results in:

Atmel AVR ATtiny2313 is found.

Page Write Disabled

FLASH Write Delay (t_wd_flash): 11111 us

EEPROM Write Delay (t_wd_eeprom): 11111 us

Uploading: flash

(total 128 bytes transferred in 1.60 s (80 bytes/s)

sure looks like success to me, but if i then read again, nothing has changed.

ideas?

thanks!

btw, this is to program an ATTINY2313-20PI on an AVR-IO-B dev board via the ICSP port.

also, if i add --verify to the uisp line, it fails to verify on every single byte:

$ uisp -dprog=dasa2 -dserial=/dev/ttyS0 --erase --upload if=test.srec --verify -v=3 -dno-poll

what ended up working for me was AVRdude – here’s my command:

avrdude -c ponyser -p t2313 -P /dev/ttyS0 -e -U flash:w:test.srec
