Week Eleven: Ping!

This is my eleventh week of being an intern at Aeste Works. My main focus this week was to ensure that two way communication between the USB stack and lwIP’s TCP/IP stack was working as intended. The simplest way to achieve this was pinging the USB CDC ECM device and Read more…

Week Ten

This is the tenth week of being an intern at Aeste Works. Continuing from last week,  I found a way to separate normal USB packets and networking packets. This can be done by checking the twelfth and thirteenth byte of the payload found in the readBuffer. Protocols such as IPv4, Read more…

Week Nine

This is my ninth week of being an intern at Aeste Works. This week was testing whether the lwIP stack had been configured correctly and whether the interface can be successfully initialized.  To initialize the network stack in a lwIP single-threaded core, the function lwip_init is called and then the network Read more…

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…

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…

LwIP on AVR32

Since the basic function for HAL is able to run without serious problem. I have to put HAL on hold and start to do net layer for AVR32. However, I will come back to HAL when bugs ‘fly’ out or when the time I want to increase the performance of Read more…
