Ticket Name: TDA2EVM5777: TDA2 QSPI flash size support

Query Text:
Part Number: TDA2EVM5777 Hello I found the QSPI flash on the EVM is S25FL256SAGMFV001 what is the max qspi size TDA support? could I replace to "1 Gbit (128 Mbyte) S79FL01GS Dual-Quad SPI NOR Flash" ? thank you

Hi, You can access 128 MB QSPI flash in CFG mode. From L3's view only 64 MB is available to QSPI (0x5c00_0000 to 0x5fff_ffff) so the maximum QSPI memory that you can access in memory mapped mode at given point of time is 64 MB only. In case you want to connect 128 MB flash part and access the second 64 MB region then you need to configure the flash so that all accesses go to the second section of the flash. These settings are provided in the flash's datasheet. Regards, Rishabh

Hi, We 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
