I have got a sample code for F28377D SDRAM I/F in controlSUITE v3.3.0.
But I found a difference in the configuration procedure between the sample code and F28377D TRM.
In the sample code, the configuration procedure below
1. SDRAM_TR
2. SDRAM_CR
3. SDRAM_RCR
4. SDR_EXT_TMNG
F28377D TRM (SPRUHM8C) says 2 way of procedures (Procedure A and B),
but both are different from the sample code.
I think SDRAM_CR should be the last step like TRM, because a SDRAM_CR write kicks a mode register configuration (LMR command)
to SDRAM.
