Hi, Im referring F429 eval board fmc sram code. For Nucleo f439, I changed to bank 1 and bank addr=0x60000000 with R/W from e.g. and init from MX tool.

The issue I see is on receive, the values are not the same (compared to TX) when buffer size>128

Can't see FMC_CLK waveforms. Configured PD3. Is is possible to have it? 

Please check

Dont see getting responses. 

1 change I see is by changing to "hsram1.Instance = FMC_Bank1E;" 

But this fails by having Fill_Buffer(uint16_t *pBuffer, uint32_t uwBufferLenght, uint16_t uwOffset), uwOffset= 0xC20F

Hope someone replies,

when clearing data with function I see 8000 instead of 0x0000
