Programming 64k EEproms

Hi Thorsten

I have accidentally damaged my 32k Bankstick.  I have made a 64k  bank version using 2 of the the Microchip 512k modules.

I am getting some strange results.  Is there anything different to the use of  the 32k version?  For convenience in wiring and using the 256k diagram I will use Banks  A = 1 and A = 5 .  At present I am trying to download to Bank 1.

Does MPLAB know or care that I am using the 64k version?

Thanks Robin

Hi Robin,

MIOS takes care about the BankStick accesses, normaly the behaviour is identical, you only have to take care for the 16th address bit (when using the MIOS_BANKSTICK_* functions: MIOS_PARAMETER2, 7)

On a 32k device this bit won't be taken into account, you will read the same content regardless if this bit is 0 or 1

On a 64k device this bit switches between the lower and upper half of the memory

Best Regards, Thorsten.
