Hi Lee, Jassi, Assuming mailbox-test was designed to be generic, I am trying to extend it to support single channel with separate Tx and Rx buffer. With these changes I am able to test arm_mhu driver. However I couldn't understand the intention of converting buffer to ASCII hex dump in read method. I have a local change to remove that so that it can deal with any data in any format(e.g. some protocol format) and userspace can deal with the actual interpretation of the data. Let me know your thoughts on that.
