Abstract

The invention discloses a boot program upgrading method, an embedded device, a control device and an embedded system. The method for upgrading the boot program in the present invention includes: receiving an upgrade instruction message sent by the control device, the upgrade instruction message is used to instruct the embedded device to monitor the serial port between the embedded device and the control device; receiving the upgrade file sent by the control device through the serial port , the upgrade file is calculated by the control device according to the file path selected by the user, the upgrade file includes file length, check field and file data; the upgrade file is written into the memory of the embedded device to replace the current bootstrap in the memory program. The invention solves the problem that the operation mode of upgrading the boot program is relatively complicated and the workload is heavy due to the need to disassemble the shell of the embedded device in the process of upgrading the boot program by using a burner to realize the upgrade.

Description

technical field [0001] The invention relates to computer technology, in particular to a method for upgrading a bootstrap program (BOOT), an embedded device, a control device and an embedded system. Background technique [0002] With the widespread application of embedded systems (Embedded system, referred to as: ES) in the field of communication and industrial control, in order to improve the life cycle of products and adapt to new business requirements, it is usually necessary to upgrade the embedded system on site, one of which is Important upgrades include upgrades to bootstrap programs in embedded devices. [0003] The bootloader of an embedded device is usually stored in a non-volatile memory, such as in devices such as NOR FLASH and NANDFLASH. The main functions of the bootloader include initializing the Central Processing Unit (Central Processing Unit, referred to as: CPU) and display data RAM (Display Data Random Access Memory, referred to as: DDRAM) and other devic...
