Hello,

Can you double-check the part number, we don't have a TUSB9321.

Thank you for your reply.

I am very sorry to make mistake on the device No.

Correct No is "TUSB9261".

Hoping to get your help.

Hello,

In order to get the code burned on the external flash do the following:

1) Download the Flash Burner utility available at http://www.ti.com/litv/zip/sllc414c

2) Download the default firmware available at http://www.ti.com/litv/zip/sllc421c

3) Use the Flash Burner to burn the external memory wit the default firmware, then you can use a generic eeprom reader to get the internal code.

Please see the Flash Burner User's Guide available at http://www.ti.com/litv/pdf/sllu125b

512Kb SPI Flash(PM25LV512A) can be observed on EVM.

Such small size is hard to obtain, now.

Is it no problem to change it to 1Mb SPI Flash(as BR25L010)?

There is no problem using a 1M flash as long as it meets the requirements described on the Section 10 of the Implementation Guide available at http://www.ti.com/lit/an/slla315a/slla315a.pdf
