Hi

I would like to ask what changes should be made in your codes so that the bootloader can be used for other cpu tips that support 64bit flash writing FLASH_TYPEPROGRAM_DOUBLEWORD.

Hi
First if all thanks for your project it’s really usefull. I’m not an expert in Java and I’d like to know if you can add a documentation to explain how to build jar file.
thanks

Can I change data in application by bootloader? For example, my app have PID and I want to change these value. If I use HAL_Flash I have to erase sector and app maybe be go wrong. I want to change just value not program. I have a idea for that. There are bootloader mode and app mode. Manually writing the required address with pointer in the application to the bootloader and change pointer value. Is there any method without erase sector?

Hi,
I'm trying to make my app1 and app2 using the arduino gui. I was going to try the Blink example as my app1 and app2 (the app1 would have 1s LED on and app2 would have 3s LED on). I found the flash.ld file and I can change the FLASH starting address, but I am having trouble with the VECT_TAB_BASE_ADDRESS and VECT_TAB_OFFSET.

I tried to define them in the Blink.ino file:

#define VECT_TAB_BASE_ADDRESS   0x08005000U
#define VECT_TAB_OFFSET         0x00005000U

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

Any ideas on how to make app1 and app2 with arduino?
Thanks.
