Stm32f103 Rs485 Bootloader
How the bootloader works. The Flash memory is divided into pages each is 1 KB and total of 128 KB (For CB version). The first sector contains the Main Stack pointer MSP, Reset handler and the rest of the Vector Table then the rest of the application follows.. By using CubeMX -which is the HAL provided by ST Microelectonics- we can read, erase and write a sector or more in run time and without

Bootloader - STM32duino wiki
This modified version of the Maple bootloader is known as STM32duino-bootloader or also bootloader 2.0. Maple devices (including clones) generally come with the original Maple bootloader preloaded. Generic STM32F103 boards on the other side come with no custom bootloader installed.

Small USB HID bootloader for BluePill and other STM32F10X
Wow, that is one compact bootloader. I've seen another bootloader that weighed in around 4KiB, but it made extensive use of hand-written assembly everywhere, particularly for the USB stack. I'm impressed. As a friendly word of advice, I noticed that you're using USB vendor ID F055, which doesn't seem to be publicly assigned by the USB-IF.

Execute from external SRAM - Spark Logic
The usb port, as it is coded in the core, should disconnect and reconnect when the board is powered up (bootloader running), when the bootloader jumps to the sketch (Sketch init code forces a disconnect, reconnect, and the PC re-enumerates the port), and same should happen when you jump from the loader to the exRAM sketch.

Jan 02, 2019 · I created a bootloader image for my STM32 and I stored it in a specific area of the memory. I have a new Keil project which represents the application layer. By default, Keil generates a HEX file. What I want to do is to keep the bootloader image and flash the application layer in another area in the memory. The final FW will verify a GPIO input.

Programming a GPS watch
Introduction. A while ago, I built a reverse geocache box from a broken GPS wristwatch (Keymaze 700 trail) found in an electronics recycle bin.For that, I had to upload a custom firmware in the STM32F103 microcontroller through JTAG (with a buspirate and OpenOCD).. The GPS wristwatch "CW Kalenji 700 gps", is very similar to the "Keymaze 700 trail", it has the same microcontroller and thus can

Microcontrollers: Why do we need a separate program in the
Answer (1 of 6): Thanks for the A2A. You don't NEED a boot loader but it is very convenient to have one. If you don't have a boot loader of any kind. The only way to put one in place is through some special tools like JTAG, ICSP etc. connected directly to the microcontroller's hardware. Lets say
