XTDA3SXXBDABFQ1: Size of On-Chip Shared Memory (RAM)

Hi,

We have been working with the XTDA3SXXBDABFQ1 for a while but now we needed to increase the size of the SBL and it got larger then 256kB. I have problem finding any documentation for this product in the TDA3X family.

When reading out the CTRL_WKUP_STD_FUSE_DIE_ID_2 register I receive. 0x98 BD 35 06. From what I can see from the documentation it is a XTDA3SX because of the 0x98.

Does this part have a 256kB RAM or does it have a 512kB?


Below you can see my System Memory Map used by the SBL. To get it to work I can't go outside address 0x00340000, so I need to have a SBL smaller then 256kB. In the config below I have configured OCMCRAM1_3 bigger then 256kbB because my new bootloader is bigger then 256kbyte.


Thanks
