Flashing precompiled binaries to an ESP32S3 using esptool

[fabianlc]

Hello, I am encountering issues when I try to flash precompiled binaries to an ESP32S3 using esptool

The command I am using inside the folder that contains the following files

Code: Select all

bootloader
	bootloader.bin
components_test_app.bin
components_test_app.elf
config
	
	sdkconfig.json
flasher_args.json
partition_table
	partition-table.bin

is:

Code: Select all

esptool.py --chip esp32s3 write_flash @flasher_args.json

inside a folder that contains the following files:


The sdkconfig.json file is autogenerated from the build process and fulfils all syntax requirements for JSON files.

In the terminal I get the following error message:

Code: Select all

esptool esp32s3 write_flash { write_flash_args : [ --flash_mode, dio, --flash_size, 8MB, --flash_freq, 80m ], flash_settings : { flash_mode: dio, flash_size: 8MB, flash_freq: 80m }, flash_files : { 0x0 : bootloader/bootloader.bin, 0x10000 : components_test_app.bin, 0x8000 : partition_table/partition-table.bin, 0xd000 : ota_data_initial.bin }, bootloader : { offset : 0x0, file : bootloader/bootloader.bin, encrypted : false }, app : { offset : 0x10000, file : components_test_app.bin, encrypted : false }, partition-table : { offset : 0x8000, file : partition_table/partition-table.bin, encrypted : false }, otadata : { offset : 0xd000, file : ota_data_initial.bin, encrypted : false }, extra_esptool_args : { after : hard_reset, before : default_reset, stub : true, chip : esp32s3 } }

esptool write_flash: error: argument <address> <filename>: Address "{" must be a number

I would be really glad if anyone can make some suggestions why this process documented on this part in the Espressif Documentation https://docs.espressif.com/projects/esp ... -arguments is giving me so much headache

The documentation refers to the text flash_args files. Notice that there are no file extension used there. You are using the JSON file, so the formatting is wrong.
