TDA4VH-Q1: Booting from Custom OSPI.

Enoch Betty

Part Number: TDA4VH-Q1

Hi Team,
We are going to receive a custom board with custom OSP for booting U-boot.
OSPI part number is : IS25WX128.
I have done some analyze about the custom chip datasheet as per the below thread link.

e2e.ti.com/.../faq-tda4vm-is-there-a-guide-to-choosing-the-right-ospi-flash-parts-that-are-supported-on-jacinto-7
1] It seems like it don't have Read Flash Array opcode.
so my doubt is whether it will affect the OSPI booting. If it will affect the booting how can I update the booting.

2] And also it seems like PAGE PROGRAM and ERASE SECTOR opcode are looks different.
For OSPI primary booting where I need to do this changes for opcode values update in BSP for booting from OSPI?

Here I have attached the datasheet for reference25LX-WX256-128.pdf.
could please help me do modification for this custom OSPI.

    Hi Team,

         Gentle remainder,

        It will be great help if you give some light on what kind of SW development effort will be required to modify the OSPI drivers provided by TI to work & boot from the QSPI device identified above IS25WX128.

    thanks.
