Part Number: AM2434

Hi Experts,

I am asking for my customer here.

When we use the EVM and OSPI Flash IO example, it can step by step run as below:

But we shield the code erased by Block below, and only keep the part erased by Sector, it cannot work normally.

And then step by step run as below, it shows the "Some tests have failed!!"

So could you have some suggestion here?

    Hi ,

    Is this a TI-EVM/LP or a custom board with a custom flash ?

    If this is a custom flash, what is the flash part being used.

    If this is TI's AM243x-EVM, the flash part used is S28HS512T. The flash has multiple modes of flash memory array.

    The configuration we have supported is 256KB uniform sector address map. To use the hybrid configuration, the (top/bottom/both) 4KB sectors needs to be configured and handled according to the sector count. After that, it can be erased with sector erase command.

    Hope it helps.

    Best Regards,
    Aakash
