At ProMik we work concentrated on perfectioning
high quality standards and technologies ever on

The Bootloader technology as well as the flashing and testing are core competencies of ProMik from the very beginning. 
 More than 25 years of experience and in-depth know-how lie behind each of our bootloader solutions - and are constantly evolving with them.

Mastering increasing requirements 
in production with reduced effort

Stricter security standards in cyber security, increasingly complex and compact components or the omission of classic test points:
The demands in production are rising and new, greater challenges have to be solved.

In its functionality, the ProMik Flash and Test Bootloader technology is both broadly based and specifically solution-oriented.
Not only is the functional scope of previous (classic) methods fully covered, but Bootloader users also profit
from an extended scope of action as well as increased efficiency and effectiveness, e.g. through shorter cycle times.

Profit through the ProMik Bootloader competencies from: 

1. Higher performance

2. Faster Performance

3. More acurate reliability

4. Contemporary security

1. High Speed Flash Programming (ISP)           

2. SMART ICT Embedded Testing

3. Cyber Security

Our proven Flash and Test Bootloader technology is a practical and high performance alternative to classic tests via test points. It offers improved functionalities to cope with the increasing requirements in production. ProMik Bootloaders can be used to implement various flash, test and cyber security functions.

The ProMik Bootloader Portfolio

Adaptable for different requirements

RAM Bootloader

For applications containing components without available test points (e.g. memory or gateways) the Bootloader is loaded into the RAM of the MCU. The therefore so called RAM Bootloader can be used for already programmed as well as unprogrammed MCUs.
The debug interface is contacted via a fixture in order to be able to control the internal applications and real-time cores. This allows the Bootloader to be downloaded to local (S/D) RAM and to be executed. Since it is a volatile memory, the Bootloader deletes itself from the RAM after programming. 
Dedicated functions can thus be used to load large amounts of data in a very short time using fieldbus communication or high speed communication interfaces.

Flash Bootloader

Especially for multi step programming processes, the ProMik Flash Bootloader is the ideal choice. After the bootloader has been programmed at PCB level via test points, the application is prepared for various tests as well as for end-of-line flash programming.

For in-package applications, the bootloader implements interfaces such as CAN (FD), Ethernet, Flex Ray and LIN to establish communication and data transfer with the hardware. After programming the ECU, the Flash Bootloader is cleared.

Functioning of Bootloaders

During booting, the hardware is initialized by activating the processor. This in turn activates various peripherals on the motherboard. Thus, either the application mode or default mode is executed. Within the default (respectively bootloader mode) default options for the application software can be executed, the application or the ECU can be reprogrammed or the software can be updated.

The microprocessor executes the startup code to prepare the execution environment for the applications written in higher level languages. In this way, the application code is started, which implements the main function of the application.

 

Concept of Flash and Test Bootloaders

Bootloaders are dedicated programs that act as startup software. They are usually started by the system firmware such as UEFI (predecessor: BIOS). The Bootloader code runs from the start of the application until the main function of the code is achieved.

The task of the Bootloader is to load the actual program into the memory as well as to update it if necessary. For this it has initialization as well as communication protocols.
