Good day! The controller has a built-in EEPROM, which is very easy to program by software.

It don't suit me.

Can I program it during pouring code via the programmer(JLink)?

I use Keil4.21

#eeprom #jlink #keil

Both Keil and JFlasher provide scripting to read/write registers and memory that might permit you to achieve the task.

In Keil Options->Debug->Initialization File

Which can use WBYTE(), _WWORD(), _WDWORD() to write to the device, before/after uploading code to the device. Try looking at some of the .INI files in the \Keil\ARM\Boards directory for a mix of examples.

JFlasher also permits custom code to be uploaded in to RAM to perform more complex tasks, which could probably also be done with Keil's scripting too, but I haven't experimented.

Keil might also permit a special template for the EEPROM region under the Flash configuration, these are applets that perform part dependent programming.

Thank You! May be the last option in more detail? I know that in the options there are 2 areas for flash-memory:IROM1 & IROM2. The address of the first I write 0x8000000(FLASH). The address of the second I write 0x8080000(EEPROM). Right? How to define an array of data in a program to burn it in the second region?
