Hi,
We are facing some issues when we move our software from dev kit to our custom hw. The major diference between hw is the memoreis size. In our custom hw we are using 16MB for RAm memory and 32MB QSPI flash for program memory. We also adjust the MCUXpresso configuration, but I think we are facing problems with the MPU setup. When I disable the MPU, the SW performace reduces a lot.
The Lvgl works very slow, but sdcard works fine... when I enable MUP, Lvgl runs fast, but Sd card stops to work
Attached you can take a look on our memory configuration on MCUXpresso and our MPU inicialization function.
Kind regards.
Solved! Go to Solution.

Hi @angelo_76 ,
Since you are using 32M flash instead, you have to update the region size as well.
Please kindly let me know if the problem is still there.
Have a great day,

Hi @Kan_Li !
Thanks for your response! I'll make the adjust and perform some tests.
Regarding to RAM memory, is it correct the adjustments that I made?
Kind regards!
Hi @angelo_76 ,
Yes, no issue found regarding the RAM configuration.
Have a great day,

Hi @Kan_Li !
I think RAM memory for custom hw is fine!
I was taking a look at flash, and I have identified the folowwing points to modify:
The source file evkbimxrt1050_flexspi_nor_qspi_config.c is related to qspi config, witch is according to the evk board. I think is necessary to change this file as well, correct?
I've highlighted the points that I think I need to change to the corresponding memory size, witch is 32MB. Could you please tell me if I'm missing any change points?
Kind regards.
Hi @angelo_76 ,
Yes , you are right, the highlight fields need to be updated according to your custom design.
Have a great day,
Kan

Hi @Kan_Li !
Looks like the changes for RAM and flash worked fine for the custom board.
I just would like to understand what is the role on the system for the source code evkbimxrt1050_flexspi_nor_qspi_config.c. Could you please give me some brief explanation or indicate a literacture about this?
Kind regards!
