N00P question - how to clear NoV64
Message #1 Posted by PeterP on 19 Jan 2009, 9:00 p.m.

Hi,

Sorry for the simple question - my NoV64 unfortunately seems to have contracted some bad code at the polling points so when I insert it my calc goes haywire. I know how to reset the NoV32 with the special .hex file from diego but I was not able to find and equivalent one for NoV64.

I tried using the nov32 one which clears things so that I plug in the module and the calc stays fine. (including on off unplug plug in cycles) However as soon as I reprogram the module, I again have garbage problems.... Is there a clear nov64.hex file?

Thanks so much

Cheers

Peter

Hi,

As some other may face the same situation and despite that I've replied your private mail on the subject...

The procedure to erase NoV-64 RAM chips is by means of CLR_RAM4.HEX file.

Burn your module with this file, make sure you have fresh batteries and plug your module in.

Your calc will turn ON automatically after 25seconds.

[CLR OK ] message will let you know that your RAM is now erased. Turn OFF and reconfigure your NoV-64 as usual.

Cheers!!

Diego.

Thanks Diego, it worked just like a charm (after I had inserted fresh batteries, it really does need fresh ones!)

Thanks as always

Cheers

Peter
