Is semi-hosting for file I/O is supported in Xtensa Xplorer IDE ?

Hello,

I am planing to implement an audio decoder solution running on HiFi4 DSP processor in i.MX RT600 EVM.

It seems like, I could connect 'i.MX RT600' with Xtensa Xplorer IDE and load my program using onboard Jtag connector.

In the initial stage of implementation, I have to test the solution using file based input/output.

That means, I have to feed the decoder running on HiFi4 core with data from a file present in host PC.
Similarly, the output from decoder needs to be written to a file created on host.

I would like to know that, whether the Xtensa Xplorer IDE supports read/write operation on a file present in host machine (semi-hosting support for file I/O)?

Thank you.

Hi Rahul,

 

If I am understanding correctly you need to read/write data from a file to the RT600 by using semihosting? If so, I am afraid that is not possible. You need to send the data to the MCU by using some interface or communication protocol, maybe using SD card or USB.

 

Sorry for the inconvenience that this may cause you.

 

Best regards,

Felipe
