TMS320DM355 --- Sample code of 'NAND Boot Mode Flow Chart' (Figure 11-8, SPRUFB3A.pdf)

Hello,

Can we obtain a sample code which shows 'NAND Boot Mode' ?

I wonder if  the titled flowchart is converted to a sample code, or some Zip file might contain a C source code.

'NAND Migration Strategies using DM3x' recommends ManagedNAND and EEPROM, although I needed to ask whether any sample code is available or not.
