PCB Design and the FreeRouting Autorouter

Work on designing the PCB layout continues in earnest. We encounter a few software issues relating to the hardware of the task, which prompt some worried thoughts. As always, here’s a look back at the previous week. Click here to skip to the conclusion. Pin Assignments During design it became Read more…

SOC with SHA1 and GPIO

This week we have managed to get an SOC that connects AEMB to SHA1 accelerator and a GPIO. Having only one device at each bus of the AEMB doesn’t require much effort in terms of SOC. The software that we used for testing contained our driver for SHA1. Our demo Read more…

Issues with Multi-Block Writing

It turns out that issue of connection timeout, random protocol data is caused by the fact I did not call the write function after TCP and Ethernet layer processes. The write function is then called in the Ethernet layer (ETH97J60.c). The function that is modified is MACGetArray(). After this modification, Read more…
