Ticket Name: TDA3: Presbl

Query Text:
Part Number: TDA3 Hi Sir, Is there any presbl code included like sbl in vision low TDA3x controller? Regards, Sagar

Responses:
Hi Sagar, I did not fully understand the question. Are you talking about ROM bootloader? Regards, Rishabh

Hi Sir, Actually in TDA2x i.e vision high there is no need to initialize QSPI while copying from external SDF. But inTDA3 i.e vision low there is need to reinitialize QSPI to do the same. Why? Also there is one presbl main function in which QSPI is initialized. So why there is again initialization of QSPI? Regards, Sagar

Hi Sagar, SBL needs to initialize QSPI as per its need. And the same is done in both TDA2/TDA3 SBL. SBL will set QSPI in 4 bit memory mapped mode. It will also change the clock to max possible for best throughput. Hope this helps. Regards, Rishabh

Hi, I haven't heard back from you, I'm assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out). Regards, Rishabh
