0x0009: The RP2350 uses XIP where firmware executes directly from non-volatile memory rather than being copied into RAM. We notice our MSP is first 4 bytes at flash followed by the Reset_Handler! THIS CAN COME IN HANDY when reversing! #Embedded #ReverseEngineering github.com/mytechnotale...

0x0008: The RP2350 boot2 config QMI for 0x03 serial reads, sets timing (short cooldown, clock div, RX delay), performs a dummy transfer to init flash & enable cont/XIP (prefix_len=0). Ret to bootrom which jmp to reset_vector. #Embedded #ReverseEngineering github.com/mytechnotale...

0x0006: Just hijacked the SRAM at 0x20000000 on the RP2350! Injected a new string in memory and patched r0 to point to our hack. Check out the proof, "hacky, world" appears at the bottom of the serial output! #Embedded #ReverseEngineering github.com/mytechnotale...

“Abstractions kill. Assembler saves!”

0x0005: The RP2350 main function continues where we step over stdio_init_all and verify that the string hello, world exists at 0x10000244 which is moved into r0 as an arg to puts. #Embedded #ReverseEngineering github.com/mytechnotale...

Will GPT replace Developers? I think the bigger question to ask is, if you had a medical device where a child, mother, father, sister, brother, wife, husband depended on AI to write the code without human oversight, would you trust that code to keep them safe? #ReverseEngineering

Working with UART we need to identify RX, TX and GND. This Netgear router has 6 pins so let’s get our tools to figure it out. #ReverseEngineering

A little JTAG hackery on a Sunday. #ReverseEngineering

0x0004: The RP2350 main function begins by pushing the r3 and link register to the stack, we see that at 0x20082000 before the push the stack has all 0's. After pushing, we re-examine the stack and see the two values in reverse order. #ReverseEngineering github.com/mytechnotale...

0x0003: The RP2350 main function begins at 0x10000234 as we can examine a non-stripped ELF binary of a simple hello world application. This is evident using GDB. #ReverseEngineering #Embedded github.com/mytechnotale...
