Hello

Currently, the customer is using CYUSB3011-BZXC.However, due to the small amount of internal
RAM, they are going to change the device itself from CYUSB3011 to CYUSB3014.

Q1) In this case, is it possible to use the CYUSB3011-BZXI  FW(HEX) as it is in 3014-BZXI?

Q2) Or it is necessary to re-build it as CYUSB3014?

Best Regards

Hi,

A1) The answer is No.

A2) The answer is Yes.

This is because the memory mapping in the FX3 device with 256 KB of SRAM (CYUSB3011) is different from that of 512 KB of SRAM (CYUSB3014).

Changing cyfxtx.c and linker is needed. Kindly check folloing KBA for the procedure.
