Other Parts Discussed in Thread: DRA829
Hi team,
My customer would like to know in order to access the entire 1Gb area correctly with 4-Byte Addressing in DAC mode, which register values should be changed ?
[Background]
The DRA829 is connected to Micron flash (MT25QL01GBBB) and the QSPI protocol is used to verify data access.
* Access is made by 4-Byte Addressing in DAC mode. (MCU_FSS0_OSPI1_R1: 0x58000000)
[Issues]
In this state, 0x58000000 to 0x5BFFFFFF can be accessed correctly, but 0x5C000000 to 0x5FFFFFFF can read the same values as 0x58000000 to 0x5BFFFFFFF.
* It seems that only 64 MByte worth of access was correctly accessed.
If you set 3-Byte Addressing and operate while switching D02-00 of the flash Extended Address Register from 000b to 111B, you can access 0x58000000 to 0x5FFFFFF correctly.
The register value of the microcontroller is basically the setting value of TI PDK, but some register values are changed for DAC mode and 4-Byte Addressing.
Thank you in advance.
Best Regards,
Kenley
