Overview The goal of this assignment is to implement a tool based on Linux Perf Events that is able to monitor main memory accesses performed by another process. For this assignment you will be allowed to work in pairs. Also, you will need to have an Intel CPU capable of recording MEM_INST_RETIRED events. Anything newer than Nehalem should do. text/html 2026-07-18T02:15:24+03:00 cezar.zlatea http://ocw.cs.pub.ro/courses/rasb/lab/hackathon?rev=1784330124&do=diff Challenge overview The Internet is unavailable, GPS is jammed, and only a sparse network of BLE gateways remains operational. Your task is to complete the firmware protocol for battery-powered rescue tags that must remain discoverable without broadcasting a permanent identity. text/html 2026-07-17T16:16:23+03:00 florin.stancu http://ocw.cs.pub.ro/courses/ass/labs-2025/05/tasks/01?rev=1784294183&do=diff 01. [Re]Configuring & building OP-TEE + ATF The initial step would be to embed OP-TEE OS into our firmware boot package and re-configure (and recompile) ARM Trusted Firmware-A to load it. But first, we need to understand the memory organization of our board. This is required since BL31 (TF-A) has to configure the TZASC peripheral to reserve a trusted region inside the main memory (DRAM) for use by our Secure OS & TAs. text/html 2026-07-17T13:29:08+03:00 radu.mantu http://ocw.cs.pub.ro/courses/ass/research/01?rev=1784284148&do=diff Research projects text/html 2026-07-17T10:11:03+03:00 florin.stancu http://ocw.cs.pub.ro/courses/ass/labs-2025/05/tasks/02?rev=1784272263&do=diff 02. Writing Trusted Applications In the second part of our lab, it's time to run some Trusted Applications (TAs)! We will use the official optee_examples as starting point. Two questions arise: how can one compile a TA? + how to test it on our board? text/html 2026-07-16T15:34:28+03:00 florin.stancu http://ocw.cs.pub.ro/courses/ass/labs-2025/04/tasks/03?rev=1784205268&do=diff 03. RAUC Finally, it comes down to installing RAUC into the Debian partitions. 📄 Our script: rauc-utils/install.sh is already complete. Feel free to read and understand it. This script will: * Mount both rootfsA and rootfsB * Uses QEMU and chroot to install: * rauc * your ca.cert.pem (certificate used to sign the update images) * system.conf * rauc-mark-good.service text/html 2026-07-16T15:25:46+03:00 florin.stancu http://ocw.cs.pub.ro/courses/?image=ass%3Alabs-2025%3Adeb-rauc-lab-skel-2026.tar.gz&ns=ass%3Alabs-2025&rev=1784204746&tab_details=history&mediado=diff&do=media text/html 2026-07-16T15:08:19+03:00 florin.stancu http://ocw.cs.pub.ro/courses/ass/labs-2025/04/tasks/02?rev=1784203699&do=diff 02. Bootstrapping Debian 2.1. Install Debian into a directory Yes, really, you can easily do this! You will use the debootstrap official tool to install a minimal Debian (you can also install deb-based derivatives like Ubuntu!) base system. 📄 Edit the mk-debian-rootfs.sh script, read the code and fill the TODOs. text/html 2026-07-16T14:40:57+03:00 florin.stancu http://ocw.cs.pub.ro/courses/?image=ass%3Alabs-2025%3A04%3Adeb-rauc-lab-skel-2026.tar.gz&ns=ass%3Alabs-2025%3A04&rev=1784202057&tab_details=history&mediado=diff&do=media text/html 2026-07-03T23:34:21+03:00 andrei.batasev http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Apupper_viz.tar.gz&ns=rasb%3Alab&rev=1783110861&tab_details=history&mediado=diff&do=media text/html 2026-07-01T17:36:08+03:00 andrei.batasev http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Abase_back_kinematics.png&ns=rasb%3Alab&rev=1782916568&tab_details=history&mediado=diff&do=media <img src="/courses/_media/rasb/lab/base_back_kinematics.png?w=500&h=369t=1782916568&amp;tok=b0a1df" alt="rasb:lab:base_back_kinematics.png" /> text/html 2026-07-01T17:25:21+03:00 andrei.batasev http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Al3_ee_kinematics.png&ns=rasb%3Alab&rev=1782915921&tab_details=history&mediado=diff&do=media <img src="/courses/_media/rasb/lab/l3_ee_kinematics.png?w=500&h=394t=1782915921&amp;tok=803bd8" alt="rasb:lab:l3_ee_kinematics.png" /> text/html 2026-07-01T17:25:21+03:00 andrei.batasev http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Al2_l3_kinematics.png&ns=rasb%3Alab&rev=1782915921&tab_details=history&mediado=diff&do=media <img src="/courses/_media/rasb/lab/l2_l3_kinematics.png?w=500&h=393t=1782915921&amp;tok=605541" alt="rasb:lab:l2_l3_kinematics.png" /> text/html 2026-07-01T17:25:21+03:00 andrei.batasev http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Al1_l2_kinematics.png&ns=rasb%3Alab&rev=1782915921&tab_details=history&mediado=diff&do=media <img src="/courses/_media/rasb/lab/l1_l2_kinematics.png?w=500&h=395t=1782915921&amp;tok=cfc878" alt="rasb:lab:l1_l2_kinematics.png" /> text/html 2026-07-01T17:25:21+03:00 andrei.batasev http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Abase_l1_kinematics.png&ns=rasb%3Alab&rev=1782915921&tab_details=history&mediado=diff&do=media <img src="/courses/_media/rasb/lab/base_l1_kinematics.png?w=500&h=397t=1782915921&amp;tok=b34d91" alt="rasb:lab:base_l1_kinematics.png" /> text/html 2026-06-28T08:52:42+03:00 jan.vaduva http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Ap_control.png&ns=rasb%3Alab&rev=1782625962&tab_details=history&mediado=diff&do=media <img src="/courses/_media/rasb/lab/p_control.png?w=500&h=85t=1782625962&amp;tok=1e76b7" alt="rasb:lab:p_control.png" /> text/html 2026-06-28T08:51:47+03:00 jan.vaduva http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Apid_eqn.png&ns=rasb%3Alab&rev=1782625907&tab_details=history&mediado=diff&do=media <img src="/courses/_media/rasb/lab/pid_eqn.png?w=500&h=40t=1782625907&amp;tok=6417ea" alt="rasb:lab:pid_eqn.png" /> text/html 2026-06-26T15:47:09+03:00 rares.sarmasag http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Anxpcar-lab.zip&ns=rasb%3Alab&rev=1782478029&tab_details=history&mediado=diff&do=media text/html 2026-06-22T17:48:14+03:00 ciprian.popescu0411 http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Alab1_skel.zip&ns=rasb%3Alab&rev=1782139694&tab_details=history&mediado=diff&do=media text/html 2026-06-19T15:10:10+03:00 vlad.radulescu2901 http://ocw.cs.pub.ro/courses/?image=rasb%3Alab%3Allm_lab.zip&ns=rasb%3Alab&rev=1781871010&tab_details=history&mediado=diff&do=media
