ESP32 Forum

Hello everyone,

for my application I would like to flash a costumized NVS partition table inside my esp32 device. The way I do this is I first create a csv file containing the required namespaces and data for my application.

I then proceed to use the nvs_partition_gen.py script that espressif provides to convert this csv file into a bootable .bin file.

Afterwards, I use parttool.py (which in itself calls esp_tool.py) to flash the nvs.bin file to the esp32 via UART:


parttool.py --port COM1 write_partition --partition-name=nvs --input "nvs.bin"

Is there a way to recreate this steps using only a jtag tool (ESP_PROG, Jlink...) without needing to use the rx/tx terminals of the esp32?

Best regards
Carlos

You could likely do it using OpenOCD, but you'd need to specify the offset in flash you're writing to rather than the partition name.

Thank you! I am sorry if I am bumping my posts, I am quite new to development and it is hard to formulate good questions sometimes.
