TMS320F280049: RAM content after reset

Hello,
what is the RAM content after reset? Where is that documented?
Especially after flashing per debugger. Customer sees all RAM content non-zero. What debug option can he use?

    Hi Holger,

    The RAM content will be zero upon a POR. This is indicated in the BootFlow diagram(Section 4.4: Device Boot Flow Diagrams).

    Upon Flashing code using a debugger, the RAM content is not all zero as the debugger uses the RAM on the device to program the flash. This is the reason why you see RAM content non-zero upon Flashing.

    One way that I think to get away with this is to issue a POR after the Flashing. That’ll ensure the RAM to be initialized.

    Hope this helps. Let me know if you have any other questions regarding this.

    Thanks & Regards
