Other Parts Discussed in Thread: HALCOGEN
hi,
I am trying to read/write to/from an external SRAM through TMS570LC4357.
Below is the brief of code:
_mpuInit_();
_mpuEnable_();
sciInit();
emif_ASYNC2Init();
EMMIFdataWrite(0x1000,0xAAAA);
EMMIFdataWrite(0x1002,0xAABB);
Data = EMMIFdataRead(0x1000);
sciDisplayData(sciREG3,&Data,2);
sciSendByte(sciREG3, '.');
Data = EMMIFdataRead(0x1002);
sciDisplayData(sciREG3,&Data,2);
sciSendByte(sciREG3, '.');
The Data write seems to be unsuccessful. If i read the location 0x1000 from above code, the data read is some random value.
I have used the 128K x 16 STATIC RAM (part # IS62WV12816ALL) as the external memory.
The EMIF address lines (A1-A16) and the data lines (D0-D15) of the microcontroller are connected to the external memory address and data lines respectively.
I have attached the HALCOgen configuration file EMIF.hcg. Let, me know if the HALCOgen configurations are wrong.
Please, do the needful.
