Program parallel NOR Flash with TMS320C6655

Other Parts Discussed in Thread: TMS320C6655

Dear All,

I am trying to program a parallel NOR Flash in TMS320C6655 EMIF16 space, but I am not able to access as short. In other terms, any access to the EMIF16 is composed by two consequent access, so, it is not possible to program the NOR sequence

0x555 0xAA 0x2AA 0x55 0x555 0xA0 ADDR DATA

What it is recommended to do in this case?

Thanks, Ivan Pessina

Hi Ivan,

Please refer to the parallel NOR flash writer code that I have shared on the following thread :

Please use this as reference to create your own writer.

Hi Rahul,

Thank You for answering me, in the meanwhile I was able to program the flash.

Anyway I did not found any low level driver in the files you attached, nor in .gel and nor the "ldd.h",

May i know how you program your flash by any application codes or what way?

Can you please share your application code which initializes and access the NOR flash from DSP.

Thanks
