Hi,

Which SDK version is being planned to be used in production?

Hi,Keerthy

We use version 3.07

Hi,

The supported boot modes in tda2xx is:

Which boot mode are you using?

Refer the below thread if you want to flash the images to the QSPI memory.

Thanks

Hi，Gaviraju

We heard that there is a small chance that TDA2 cannot be booted from QSPI FLASH, when the hardware does not disable the SD card of TDA2, and the hardware has been set to two boot modes (SD card and QSPI FLASH).

I want to confirm if there are other customers reporting this issue? Do we need to change our current hardware BOOT configuration?

Our BOOT mode is shown in the screenshot,  The TDA2x TRM version is Silicon Revision 2.0, 1.1

SDK  version 3.07

Hi,

On your board when you do not have the SD card with the above dip switch settings are you seeing
that you see u-boot coming up from QSPI?

yes,  when I do not have the SD card with the above dip switch settings  , u-boot coming up from QSPI  is OK .

Hi,

So the question is mainly with the consistency of the QSPI boot as back up boot mode when SD is primary correct?

- Keerthy

YES , 

How can I solve this problem without changing the hardware BOOTMODE setting?

It seems that he has not solved this problem

Thanks. I will check on this internally & get back by next week.

Hi,

Hi，Keerthy

The hardware we designed requires a QSPI FLASH boot mode, so which boot modes TI recommends us to upgrade the code of QSPI FLASH without such problems?

Best Regards

Hi,

Could you please describe a bit more? I did not follow. QSPI as primary boot or secondary?

- Keerthy

HI,Keerthy

Our products are mainly started by QSPI_4 boot. According to the requirements of Table 29-9. Booting Devices Order in the TRM manual.

When QSPI is used as primary, is it necessary to use "Automotive Production Booting" in automotive product applications? Is there anything wrong with using "Memory Preferred Booting" (0b10 0b0111) for automotive products?

When QSPI is used as secondary, is there anything wrong with using "Peripheral Preferred Booting" (0b00 0b0111) in automotive products?

Best Regards

Hi,

I am yet to get a response from our RoM expert. I will keep you posted.

Thank you Keerthy ,

According to our current boot configuration(sysboot[5:0]=000111）, it seems that as long as the SD card is not inserted, there is no QSPI boot  failure problem.

By the way, is this problem in this Errata document? It seems that I did not find the relevant one!
