4.1.2.2.5 Programing Program memory
Before performing this function, you must ensure that the target chip is connected and encryption is not turned on in order to operate!
By programming the Program memory function, the firmware loaded by the user is written to the target chip code space, and the source of the written data depends on the following two cases:
When the chip firmware (bin, hex, s19, elf) file is not added, the entire editor buffer will be written.
When a chip firmware file is added, the starting address and size of the data that is written, depends on the file that is added, but the source of the data still originates from the editor buffer, which means that there are the following states.
- When a file is added, data will be copied from the file to the buffer, and any unsaved data in the buffer will be lost.
- When reading the target chip data, the data will be copied from the target chip to the buffer, at this time, the file can be exported, such as when re-clicking the application firmware, the buffer data will be overwritten.
- When editing the buffer directly, the original firmware file will not be modified directly, and when the editing is finished, click Program Program memory to write the modified buffer data (overlap with the added file) to the target chip.
The operation demonstration flow is shown below:
tipThe buffer editor serves as a staging state for the PowerWriter to communicate with the target chip, and is applied flexibly in different scenarios.
4.1.2.2.6 Verify program memory
- Before performing this function, you must ensure that the target chip is connected and encryption is not turned on in order to operate!
- With the checksum function,data comparison can be performed directly without reading the firmware's checksum value (CRC32, Check Sum).
Through the Program memory verification function, you can compare whether the currently loaded data and the target chip are the same, before verification, please load the PowerWriter project or add the firmware of the chip that needs to be verified for comparison, the operation flow is shown below:
4.1.2.2.7 Automatic programming
Before performing this function, you must ensure that the target chip is connected and encryption is not turned on in order to operate!
Program memory auto-programming will automatically erase, program, and verify the code space. Erase Program memory、Programming Program memory、Verify Program memory, The operation demonstration is shown below:
4.1.2.2.8 Full automatic programming
Full-featured auto-programming will automatically complete a series of processes according to the current project settings, such as writing option bytes, serial number, Matrix signature information, automatically selecting the erase method, automatically completing all the data programming, checking, and completing the subsequent actions after the end of the burn-in, such as resetting the chip to run, etc., simplifying the complexity of the process, a one-step completion of the process. In most of the time, this function can realize online one-key programming, the demonstration flow is shown below:
Full-featured auto-programming, does not support plug-in functions, such as UID restriction, SN restriction, factory test, some special chip customization plug-ins, such as STM32WB protocol stack upgrades, STM32H5 security configuration and other extended functions, if you need to perform the extended functions, please use the offline burn-in mode.
4.1.2.2.9 Other data area operations
Other data area for the dynamic data area, all the chips have Program memory area (code flash), in addition, some of the chips also contain some specific storage areas, such as EEPROM, USER DATA, OTP, BOOT and other areas, although the name of the strange, but the function is the same, is mainly divided into three types of storage areas:
- Stored data: EEPROM, USER DATA, etc.
- Stores data and can only be programmed in a single pass: OTP
- Storage code: BOOT, STACK, APP, etc.
The function of this area, the operation of the same Program Memory operation, in addition to OTP, are supported to read, check the empty, erase, program, verify and other operations, the following selection of different chips to demonstrate the dynamic tabs, as well as the function, as shown in the figure below:
