Part Number: TMS320F28377S
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hi

My customer is developing their own code based on sample project of emif_dc_cpu in C200ware.
When an array data as unsigned integer is written to external SRAM, the elements with even index are overwritten with the values ​​of the elements with the next index.
Could you show me expected causes or any idea to analyze the cause?  

The details are shown in the attached excel file.Details.xlsx

The following file is compressed file of the project.

emif_dc_cpu.zip

Best Regards, Taki

    Taki-san,

    I recommend using the C2000-EMIF_ConfigurationTool.xlsx (from ~\C2000Ware\boards\TIDesigns\F28379D_EMIF_DC\) to validate the EMIF configuration for the SRAM.  This related EMIF appnote also provides some guidance on how to approach common problems.
