Tool/software:
Hello,
We are developing a system using the TDA4VEN-Q1 device.
I would like to ask about the flashing procedure in the following situation:
-
When the BOOTMODE pins are configured as Primary: OSPI and Backup: None, is there any environment or supported method to perform pre-flashing (i.e., flashing during manufacturing)?
Background
In the MCU+ SDK examples, the typical flow is to boot in UART mode, flash the SBL, and then change the BOOTMODE pins to OSPI boot.
However, in our production environment, we plan to fix the BOOTMODE pins completely in hardware and do not want to change them after assembly.
Therefore, we would like to know the general or recommended method to flash the SBL and other images to the OSPI NOR Flash externally, when the BOOTMODE pins are permanently set to OSPI NOR Flash boot.
We are not limited to a specific approach — we simply want to understand what TI generally assumes or recommends for manufacturing-time flashing in such a configuration.
Thank you in advance for your support.
