TDA4VM-Q1: TDA4 OSPI can not boot up

Part Number: TDA4VM-Q1

Hi TI Expert,

1. OSPI flash type:

The OSPI flash used on TDA4x EVM is MT35XU512ABA which the working voltage is 1.8V, we chose MT35XL512ABA which the working voltage is 3.3V.

The software can run TDA4x EVM, but it can not run our customized development board after we modified OSPI flash chip ID;

we hope boot up mode: OSPI+EMMC(First boot up from OSPI, then jump to EMMC), SDK 7.1

2. when we program OSPI flash, chip ID can be read;

we notice the relevant link: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/902918/processor-sdk-dra8x-tda4x-ospi-flash-driver

Please see source code below, the following TI original default function can not get OSPI chip ID and configuration;

Please give us suggestion, do we need additional compilation tool on PC side to compile TI default library to support  MT35XL512ABA?

or modify some source code, script, DTS, header file, SPI-Nor-flash driver(drivers/mtd/spi-nor/spi-nor.c) ? please specify file path what we need to modify;

3. UART_socGetInitCfg(Borad_UART_INSTANCE, &uart_cfg)

OSPI startup flow involve following 3 steps as our understanding, the first step was comleted by TI library, the second/third step was operated by us.

1) SBL UART: does TI Library read OSPI chip ID and configuration at this step?  it fail to read OSPI chip information at first step,

Can we modify this part of TI library with other compilation tool to support  new MT35XL512ABA OSPI at host computer ? 

Or we can ignore this error log information and enter next step 2) ?

2) SBL OSPI: we can modify this part of source code at this step, software can identify OSPI chip ID and configuration. 

3) Kernel: we can modify this part of source code at this step too, software can identify OSPI chip ID and configuration. 

4. Please see console log information below:
