External SDRAM network error

[cshsoft]

Hello everyone,

I have a question to ask, and it is wrong to transplant the netxduo to SDRAM, but it is ok to compile the code to the STM32H7 internal sram.

Thanks for reaching out! Are you trying to move packet pool to SDRAM or execute NetX Duo from SDRAM?

[cshsoft]

Yes, because the built-in Flash capacity of some chips is not enough, we need to run most of the code in SDRAM. At present, I allocate the data pool in internal SRAM, but it is better to put all the code in external SDRAM, I wonder if there is a suitable solution

It looks like the issue is specific to MPU configure for ST. Did you try to contact ST? Here is the ST support website,

I may have found some problems with network byte order and SDRAM's default storage sequence
