What is the differences between: 1.Remapping memories to processor code region and 2.Executing the program code built with absolute addresses without remapping I read something about executing multiple image in a microprocessor (ARM Cortex-M3) and i'm ambiguous about differences between executing with remapping image to "code space" and without remapping? I would be grateful if you help me ...

The popular GNU-ARM toolset has had long-known issues for the Cortex-M0/M0+/M1 (ARMv6-M architecture). Specifically, people have reported very inefficient code generated, see "Cortex M0/M0+/M1/M23 BAD Optimisation in GCC" https://embdev.net/topic/426508 . But while so far people reported only inefficient code, I would like to make people aware of *incorrect* code generated by GNU-AR

hello: Hello: i am using ov7690 with at91sam usin MCK at 12.3MHz. but for testing purpose i am using I2C at 153KHz from atmega2560 for SCCB. I can read any register from ov7690 but I can't write to any register. the response is correct i.e. status register of TWI of atmega2560 depicts correcr value, meaning it sends data. but when i read back the value from that register the ol...

There are many MCUs with embedded Ethernet (MAC). It seems most of the open-source examples are lwip-based. I have to design a board with one RS485 port and one Ethernet port. It could be seen as a serial-to-Ethernet converter, where the protocol on RS485 is proprietary. On Ethernet side I will contact a server (cloud) with a protocol that must be defined. At the moment, I don't need...
