Hi RandyP:

I have some problems about C6455 SRIO boot.I hope you will give me some suggestion.

Now I want to make my dsp work on slave Srio boot.In my case,i use a fpga write code and data to the dsp through rapid io.But acording to the document C645x Bootloader User's Guide.It doesn't tell me how to create the image that need to burn to the mater device.

Can you tell me something about this?Thank you very much.

This needs to be a new thread since it is a new question and the other one was marked as answered.

Please follow the same instructions as listed in spruec6g section 6.1 Host/PCI.

Is there some examples for C6455 SRIO BOOT?

And thank you for your help before.

The examples in the application note that are for Host and PCI also apply for SRIO.

Your host side must take the file you create and write the data to the DSP over SRIO.

Hi RandyP:

Thank you for answering my questions.Now I create the image that i need successfully.

And one more question.Since the rapid IO is always transfer the data in the multiple of 8 bytes.That means I need to make the data of each section multiple of 8 bytes,am I right?For example,I add data 0x00 at the end of the section.

Please direct me to the documentation that specifies an 8-byte transfer multiple. Please give me document name, page/section, and paragraph. I am not familiar with this limitation.

Acording to the documents Creating a DSP Boot Image for Host Boot(sprab60).I create the image that i want.And now I have some other questions.

1.At the beginning of the srio boot,I don't have to do anything about the slave dsp.Am I right?

2.The document says the host send a doorbell interrupt and the cpu then begins executing at the base of L2.In the dsp c6455.We can send doorbell interrupt with information 0-f,20-2f,40-4f,60-6f.Which correspond to the DOORBELL_ICSR0--4.In order to interrupt the slave dsp to execute at the base of L2,which doorbell info is right?

3.In the document of C6455 BOOT UG,it says the device ID = 2 + BOOTMODE[2]:CFGGP[2:0].I configure the BOOTMODE[2]=1,CFGGP[2:0]=000.So my device ID of the slave dsp is 0x0a?

Looking forward to your answer.
