srec_ Use of common cat parameters

Preface

Here is the image file tool srec_cat Use , How to realize the functions you need through relevant parameters .

Download link ：SRecord

Usage mode

file type

When inputting and outputting files, the file type should be indicated , Commonly used as ：

test.hex -intel
test.bin -binary

File conversion

You can enter file type conversion through this software .

Such as hex File transfer bin file ：

srec_cat.exe stm32.hex -intel -offset 0x08000000 -o stm32.bin -binary

take stm32.hex from 0x08000000 Address starts to be converted into bin file .

bin File transfer hex file ：

srec_cat.exe stm32.bin -binary -offset 0x08000000 -o stm32.hex -intel

take stm32.bin The offset 0x08000000 Address starts to be converted into hex file .

File capture

If you need to intercept part of the file , You can use parameters -crop.

srec_cat.exe stm32.hex -intel -crop 0x08000000 0x08003FFF -o stm32_app.hex -intel

take stm32.hex In file 0x08000000 - 0x08003FFF The valid data in generates a new file stm32_app.hex, If the end address of the code is 0x0800 1FFF, Then the code range of the newly generated file is 0x08000000 - 0x08001FFF.

Content filling

character string

If you want to fill in the string information at the position specified in the file , Such as version information

srec_cat.exe -generate 0x08000000 0x08000005 -repeat-string STM32 stm32.hex -intel -exclude 0x08000000 0x08000005 -o stm32_new.hex -intel

stay 0x08000000 0x08000005 Repeat filling in the range of “STM32” String information , and stm32.hex （ Exclude 0x08000000 0x08000005 Range data ） A merger , Generate new files stm32_new.hex

• -generate： Data generator parameters , Address range - data source
• -repeat-string： String parameters , Access string parameters later
• -exclude： Exclude filter parameters , Does not include data in a certain range of memory
• repeat ： If the string length is less than the reserved range , Then repeat filling , For example, will 0x14 Change it to 0x16, be 0x15 and 0x16 The data corresponding to the address is ‘ST’

Numbers

If you want to fill in digital information at the location specified in the file , Such as file size

srec_cat.exe -generate 0x08 0x0C -constant-l-e 0x123456 4 stm32.bin -Binary -exclude 0x08 0x0C -o stm32_new.bin -Binary

stay 0x08~0x0C Fill the range according to 4 Byte repeat fill 16 Hexadecimal Numbers 0x123456, and stm32.bin （ Exclude 0x08~0x0C Range data ） A merger , Generate new files stm32_new.bin

• -constant-l-e： Numeric value byte width parameter , Instant value - Byte width
• repeat ： If the alignment length is less than the reserved range , Then repeat filling , For example, will 0x0C Change it to 0x0D, be 0x0D The data corresponding to the address is 0x56（ The small end model ）
