How is flash memory divided on the stm32f103c8t6?
The STM32F103C8T6 does not have NVM like this but it’s Flash program memory can be used with care for the same purpose. The Flash memory in this chip is divided into 1kiB sectors and there are 64 if them (0 to 63). The code to erase, write and read a sector is shown below:
How to upload stm32f103c8t6 USB bootloader?
In the Arduino IDE, go to Tools and make the necessary changes to the board selector as mentioned in the “Getting Started to STM32F103C8T6” guide. But you need to change the Upload Method option to “Maple DFU Bootloader 2.0”.
Is it possible to flash stm32f401cc-j-link?
1st I checked the NRST Pin of the processor with a scope, and yes, the RESET pin goes low and high again when a debug session is started, rise time is approx. 10ms, that looks ok to me. Then I connected the board with an St-Link/V2 using openocd in Eclipse. Well, that works!
Is it possible to erase a sector of flash?
Erasing flash [100%] Done. Verifying flash [100%] Done. J-Link: Flash download: Restarting flash programming due to program error (possibly skipped erasure of half-way erased sector). J-Link: Flash download: Skip optimizations disabled for second try. Error while programming flash: Programming failed.
How is flash memory used in a microcontroller?
Some microcontrollers have a dedicated Non-Volatile-Memory (NVM) bank for storing calibration data, program settings and so on. The STM32F103C8T6 does not have NVM like this but it’s Flash program memory can be used with care for the same purpose. The Flash memory in this chip is divided into 1kiB sectors and there are 64 if them (0 to 63).
What is the sector start address of flash memory?
The sector start address must be on a 1k boundary. In this chip, Flash memory starts at 0x8000000 so sector start addresses can be 0x8000000, 0x8000400, 0x8000800, 0x8000c00, etc. The data sheet states that the flash can withstand at least 10000 write cycles (does this include erases?).
