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…
This is my eighth week in AESTE WORKS. I should put my work in Git release branch by Tuesday, but I only managed to do it on Thursday. This is due to I faced a few problems there. The flash memory cannot be read/ write. PIC32 cannot get the IP Read more…
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…
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…
This was my second week here. I was tasked with troubleshooting and characterizing the boards. There are in total seven prototypes for me to play with. The boards are divided into old and new boards. The main differences are that the new boards use slightly different PIC32 and Spartan-6 chips. Read more…
This week I dig deeper into identifying the TCPIP Stack bug. Ideal Case Based on the document UG380 and XAPP502, ‘init_b’ of FPGA should be HIGH (reading from PIC32), if it was LOW during configuration means there is an error, ‘init_b’ can also be pulled LOW to delay configuration, in Read more…
This week I continue trying to figure out how to ‘download’ a huge file with TCP protocol. Set up a USB cdc com port to ease debugging. Fixing ‘init_b’ staying LOW. TCP Server looping READ socket To be able to ‘download’ or I should say read a file being uploaded Read more…
This week I integrate my previous TLS TCP Server code onto ‘the board’ – PIC32MZ. DHCP enabled & Fixed IP adress test First I experiment with having DHCP enabled on MHC. Using ‘tcpip_discoverer’ from Harmony to fetch the assign IP address. java -jar tcpip_discoverer.jar The discoverer tool is very useful to Read more…
This week I test the board that I design. The details of the board are explained in previous post, my first objective would be to be able to program the PIC32, confirm the osciallator is working, able to communicate with a LAN8720 to have internet connection. Programming PIC32 To program Read more…
This is my eighth week in AESTE. Continue working on PIC32 with DM320004, however this time rather than focusing on MLA code, I shifted to use Microchip Harmony source code on PIC32. ┏(-_-)┓┏(-_-)┛┗(-_– )┓┗(-_-)┛┏(-_-)┓ ┏(-_-)┛┗(-_– )┓┗(-_-)┛┏(-_-)┓┏(-_-)┛┗(-_– )┓┗(-_-)┛┏(-_-)┓┏(-_-)┛┗(-_– )┓┗(-_-)┛┏(-_-)┓ The advantage of using Harmony is that most of the driver, third Read more…
