Sequence RAM memory RT1051/RT1052

[rubensjunior]

Hi friends,

I am development a project (RT1052) where I do not have Flash memory. Then, all my code is in RAM memory (internal RAM + external RAM). However, when I put the external RAM in first position, ocuors the bellow error when is executed.

When I put a internal RAM in first position work fine, but not have enough space for save me code.

Please, I need your help!

Hi Rubens Junior

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
You'll basically need to write and then a script that pokes the appropriate registers to set the SDRAM up before your debug session attempts to download the code into the RAM.
I've attached a script, so please follow the figure to add it before debugging the project.

Have a great day,
TIC
