The EVM of TDA4V mid used OSPI flash MT35XU512ABA1G12-0AUT and Hyper flash S71KS512SC0BHV000, could it change to use QSPI flash or other source ? Any AVL for TDA4V mid ?

Hi,
Are you asking if the device/design supports QSPI flash? There is a NOR flash (MT25QU512ABB) on TDA4x EVM which is connected to OSPI port 1 in 4-bit mode. Please check if this what you are looking for.

Hi Pratap,
Thanks for your reply, so we only can connect QSPI flash(4 bit) on OSPI port 1, right?
Does it has any indicate part for OSPI flash? Can we change to other source ? such as Cypress S25FL512S .
Another question, could you let me know the function for 1-Mbit boot EEPROM, is it necessary?
Thanks a lot.

Hi,
Yes, OSPI port 1 functionality is limited to 4-bit (quad) mode.
You should be able to use any OSPI device which is compliant with standard flash commands/modes. Let me check if there are any dependencies for the boot and get back to you.
Boot EEPROM on the EVM is for demonstrating I2C boot of the device. You can choose it based on your design/application needs.

Hi Pratap,
Do you have any update for "any dependencies for the boot" ?
As your feedback the i2C boot EEPROM is not necessary so we plan to use one O-SPI flash for boot ROM.
Thanks a lot

Hi,
I am assuming you are going to connect Cypress S25FL512S to OSPI port 1 in quad mode and use it with qspi boot.
This flash device is compatible with RBL for qspi boot. Basic requirement is to support quad read (0x6B) command to be able to boot from qspi flash.
