Yes, you can open a .bin file on an iPhone, but it depends on the type of .bin file and the apps you have installed on your device. Most email clients, as well as service providers, allow the use of the bin file extension as email attachments. Since the data present in such files are of a varied nature and can even be present in a compressed state, such files are not usually blocked. In iOS, you can use the “Archives” app, which is capable of opening many kinds of compressed files, including the bin format.
Linksys has custom footers with Checksum checks, hence this script was written to try and automate the process of calculating the checksum of the image and changing the footer accordingly. If you need to make a certain change to the configuration, you would have to re-flash the firmware and compile it, basically repeat the process all over again. On the positive side, Marlin has great documentation, a huge community, and a wealth of material available online to learn and get help from. The online configuration tool makes RepRap stand out, giving it the ease of use many 3D printer users desire in Marlin. Your 3D printer may or may not have a bootloader, depending on what printer you have. Finally, you would click on “Firmware Update” and all the relevant information will pop up, including the current firmware version that your printer is using.
You should also have your device connected to the USB port, either directly or with an adapter. From the espressif firmware you just downloaded you will need to load 4 seperate files to the ESP8266 chip. The easiest way to determine the flash capacity is to load the firmware and then print(node.info’hw’.flash_size) which reports the flash size in Kb. Alternatively, if you want to determine the capacity of the flash chip before a firmware is installed then you can run the following command. This will return a 2 hex digit Manufacturer ID and a 4 digit Device ID and the detected flash size. If you have chosen the right COM port and right binary, it will be flashed within 5-10 minutes. After that you will be able to use Arduino IDE to upload codes to your NodeMCU (ESP8266) module and program it for the next best IoT device.
In some cases, sections within the firmware may be encrypted or compressed. If compressed, it is common to find some signature identifying the format, although it does not always exist. However, identifying an encrypted section requires another type of analysis. In the IoTGoat-raspberry-pi2.img firmware itself there are also FAT16 and FAT32 tags, but these file systems do not contain files of interest. They are used to allow writing the image to a USB flash drive.
