Hi,

I have another related question about the serial EEROM.

The LogicLoader Addendum (PN: 1003421 Rev. A) states that size of the serial EEROM is 128 bytes (in the table at the start of Section 2.1).

The hardware specification for the board (PN: 10061624 Rev. E) states that the size of the serial EEROM is 4 kbits (which is 512 bytes).

Is this an error? Or does this imply that the first 128 bytes are reserved for LoLo and that the remaining memory is available for the application?

FYI: I plan to use a serial EEPROM boot script to load and execute Windows CE and an application. However, I also would like to store user data in the serial EEPROM.

Thank you.

Hello Guy,

If you were interested Logic could provide a Windows CE driver under contract. Please contact your salesperson to obtain a quote for this work.

You can also check the BOM for the card engine to verify the size of the EEPROM that is on your card engine. We are going to be making a change to the docs since there appears to be a mistake.

Thanks,

Hi,

The BOM shows two serial EEPROMs one is a 256 byte part and the other is 4 kbit part. The schematic shows that the 4 kbit part is the one I'm interested in.

Do you know the answer to my original question, i.e., are there any reserved parts of the serial EEPROM (aside for the part I am going to use for the boot string)?

Guy,
LogicPD Logic Loader software reads out the first 4 characters from the EEPROM and if they are "VOLO" or "LOLO" Logic Loader continues to read out the EEPROM and parses the data as a Lolo script. If the user doesn't store a script in the EEPROM, or the script is short, the remainder of the EEPROM is available for customer data storage.

Regarding winCE drivers, we do have winCE drivers available for our LH7A400-10 and LH7A404-11 products, however, one is not currently available for the PXA270-10 product.

If you were interested Logic could provide a Windows CE driver under contract, or another route you may want to take would be to purchase the source code for an existing driver EEPROM driver on our other products and port it to your application. Please contact a EPSsales@logicpd.com to obtain a quote for either option if you'd like to pursue.

Thanks!
