I spent this week measuring the TCP performance of the CORS program. We wanted to know how fast can the board actually perform from a network perspective. I collected data on multiple parameters that I’ve determined to have a considerable impact on speed. I was appalled to find out that Read more…
This makes my 11th week with Aeste. I started off by implementing the generation of the RNG key which is to be read from the flash and performing even more trials to make sure it works exactly the way I believed it did, which Dr. Shawn stressed. Because most interns including myself half-ass everything Read more…
I started off this week by troubleshooting and testing the flash functions. In harmony there are two non-volatile memory drivers, NVM and Flash. Usage of the flash driver is simpler compared to NVM. The functions allow you to write a word, quad word, or a defined row size. Though you Read more…
I spent this week jumping between tasks as I tend to get bored working on the same thing for long. This week I worked on implementing HOTP, flash and troubleshooting the SSL server. HOTP works by computing an HMAC based on 1- A static secret key generated by the server and Read more…
Eighth week. Slow. I did not manage to implement HOTP nor SSL. My cryptography knowledge is weak. I had a ton of studying to do and even more still. As for SSL, with some slight troubleshooting it should work soon, but its not a priority at the moment. Flash code is also not Read more…
My task for last week was to implement CORS protocol for the HTTP server on FreeRTOS with the new boards. To briefly explain, when accessing an HTTP website (server) your browser (client) is sending a request to the server (GET request) asking for data. If you’re on chrome hit F12 go onto network tab Read more…
This week I pushed my basic FreeRTOS port onto a release branch on GIT (yay) as functionality is good. It’s very simple. It has 3 apps related to USB, FPGA and TCP/IP. The USB CDC app task maintains the state of the driver and creates another task whose job is checking the status of certain global Read more…
Week 5. I continued working on utilizing FreeRTOS for our board as last week I had done a very improper implementation. In my inexperienced eyes, everything was working, but more and more issues were appearing. That’s when Dr. Shawn took a look at the chaos I’ve created. Basically I didn’t understand well Read more…
This week I was tasked with migrating our PIC32 code so it would use the superior FreeRTOS architecture instead of a superloop. Having no experience in FreeRTOS whatsoever I began by skimming through the first 3 chapters of documentation to get me started. Later I simply enabled the FreeRTOS third party library in Harmony Configurator Read more…
It’s already week 3. Time flies on internship. Its really not boring either. I sometimes spend +8 hours in the office but I’m never thinking “Oh man when can I leave?” Instead its “shit I’ve been here for 10 hours I should probably leave”. This week’s work was a continuation of last weeks’. First Read more…
