Hi,

I'm using the EVM-243x with TCP server example

I'd like to add functions in the FLASH.

Is it OSPI or QSPI device ?

I have the following line in the linker FLASH : ORIGIN = 0x60200000 , LENGTH = 0x100000

if I put a function in the FLASH - can it harm the boot loader ?

Which addresses of the FLASH are safe to use ?

Thanks,

Eli

Hi,

Another question:

I see that there are two FLASH memories on the EVM

16GB - eMMC

64MB - OSPI

Where from the boot runs ?

At which FLASH can I put my functions to avoid conflicts with the boot ?

Thanks,

Eli

Hi,

I've still working with TI representative (Aakash) on the issue, so I've got the explanation.

Thanks,
