Part Number: TMS570LC4357
I am trying to read/write to/from an external SRAM through TMS570LC4357.
Below is the brief of code:
_mpuInit_(); _mpuEnable_(); sciInit(); emif_ASYNC2Init();
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.
Thanks and Regards,QJ Wang
