eeprom problems

Otmar

Hello all,

i have a problem with the NS_eeprom_drv.010 located on the Hydra CD.
The driver does not work correctly then i write more than 2^15 bytes (32768 bytes) to the eeprom.
I dont know if the read or the write function is not working.
Is their maybe a newer version of the driver?

I am using the Hydra-Board withe the AT24C1024 eeprom.

Thanks

Hmm, I would read the driver's docs carefully, but there are addressing issues you have to handle properly, otherwise, it rolls over. It's been a while since I played with it, but give Rich Benson's "HAM" tool a try, it works with the 128K eeprom and I think uses our driver as well, see if that works fine, then you can go from there. The HAM driver tools are on this site, and sourceforge.

Problem is solved!

In version 1.0 of the eeprom driver is a bug.
One constant is wrong : addr_msb_mask long 1<<17 should be addr_msb_mask long 1<<16 then everything works fine.

In version 1.1 the bug is solved. I found the version 1.1 in the package of the "HAM tool".

Thanks for your help
