Week Eight

This is my eighth week of being an intern at Aeste Works. This week was about setting up and integrating the lwIP stack with the USB CDC ECM device. The device currently does not run with an operating system and so must be configured for the lwIP¬†NOSYS mode¬†using the raw Read more…

Reaching a Milestone

So I managed to implement the reusing of private keys as part of the renewal process. The problem was that I was calling the wrong API for Botan, which yields an unexpected outcome. Shortly after that, Dr Shawn wanted me to implement one more feature for the application. It basically Read more…

Week Seven

This is my seventh week as an intern at Aeste Works. This week was about figuring out which part of my USB CDC ECM code interfaces between the host and device in sending and receiving network packets so that I could integrate the lwIP TCP/IP stack later on. There are Read more…

Week 2 in 2019

Nothing much to be said for this week. I attempted to implement based on what Dr Shawn suggested to me last week, i.e storing the public and private key pairs in the database, so that the private key could be reused for subsequent certificate renewals. This relies on the user Read more…

Week Six

This is week six of my internship at Aeste Works. After configuring the company’s board to enumerate successfully on a Windows environment, it was time to configure it on Linux. On Windows, the usb drivers loads according to the Vendor ID and Product ID which was for Microchip’s USB CDC Read more…

Connecting Wishbone switches

I continued to work on the Wishbone switch throughout the week. First of all, I added some additional signal ports to the Wishbone switch I created last week. Those additional signals were described as follows, based on the Wishbone specification. MASTER signals SEL_O: It denoted the location of valid data. Read more…

A tale of a Wishbone switch

I was working on a Wishbone switch in this week. The switch would be able to pass data to either the downstream or the I/O device from the upstream. To design a Wishbone switch, it was crucial to understand all signals present in Wishbone. I would describe some Wishbone signals Read more…

Week Five

This is week five of my internship at Aeste Works. To move forward to what I have to do to implement USB CDC ECM class for ethernet over usb, I’d have to first migrate the USB CDC ACM demo from the PIC32MX which I had been working on last week Read more…
