General issue report

I wanted to create a single app image for my project the partitions table is as follows

factory, app, factory, 0x010000, 4150K,
model, data, spiffs, , 3750K,
nvs, data, nvs, , 16K,
fr, data, , , 128K,

I used the command esptool.py --chip $esp32s3 merge_bin -o $main.bin "@flash_args

But when the generated file is flashed The program is not running properly. what should be done to fix this issue ?

@MR-VENOM, did you tried flashing this same file with esptools.py? What address is this merged binary expected to be flashed at?

[MR-VENOM]

@adwait-esp Sorry for the late reply... The address to be flashed is 0x0 and the merged bin never worked for me but flashing with esptool.py with below command works fine :

python -m esptool --chip esp32s3 -b 460800 --before default_reset --after hard_reset --no-stub --port /dev/ttyACM1 write_flash --flash_mode dio --flash_size 8MB --flash_freq 80m 0x0 bootloader/bootloader.bin 0x10000 ai-module.bin 0x8000 partition_table/partition-table.bin 0x41e000 srmodels/srmodels.bin

@MR-VENOM - is this issue solved for you?
In the esp-launchpad there is also an option "DIY" to flash individual 4 files at respective 4 addresses i.e.
0x0 bootloader/bootloader.bin
0x10000 ai-module.bin
0x8000 partition_table/partition-table.bin
0x41e000 srmodels/srmodels.bin

Have you tried selecting 4 different files and flashing instead?

[MR-VENOM]

@adwait-esp No the issue is not solved , yes i know about DIY option for me i need to have single bin for production use case

[adwait-esp]

@MR-VENOM Can you try below, this should ideally work.
esptool.py --chip esp32s3 merge_bin --flash_mode dio --flash_size 8MB --flash_freq 80m 0x0 bootloader/bootloader.bin 0x10000 ai-module.bin 0x8000 partition_table/partition-table.bin 0x41e000 srmodels/srmodels.bin -o merged.bin

Would it be possible for you to dump the contents of the flash_args file of yours?
