Hello Team,
We are planning to use ESP8684-WROOM-05 (H2 or H4) module into one of our products where it will be used for BLE and WiFi related communication and connected with other Master Host MCU.
I have checked into ESP IDF but didn't find any target for ESP8684-WROOM-05 or EP8684 SoC based target selection and compilation perspective.
So, would you please help us like how to start development like it is AT command based or can develop like ESP32 Target? Please share details if any for ESP8684 module development.
Let me know if need anything else from my end.

The 8684 is a variant on the ESP32C2, so you should select that chip to program it.

Thanks a lot @ESP_Sprite for your prompt response.ESP_Sprite wrote: ↑Thu May 23, 2024 2:29 amThe 8684 is a variant on the ESP32C2, so you should select that chip to program it.
We will check with ESP32C2 Target from our end and will let you know if any further query for the same.
So, I would like to know that is there any other configuration is required for ESP8684-WROOM-05 module based on ESP32C2 Target?
We will also study datasheet for ESP8684 Target from our end and will let you know if any other query regarding same.

Re: Looking support and help to start ESP8684-WROOM-05 Module Development
Hello Espressif Team,
I would like to confirm that below are correct flash location to flash bootloader, partition image and application firmware file accordingly?
0x0 build/bootloader/bootloader.bin
0x8000 build/partition_table/partition-table.bin
0x10000 build/hello_world.bin
Because into earlier we were using ESP32 based chipset in which we are generally using following flash location
0x1000 build/bootloader/bootloader.bin
0x8000 build/partition_table/partition-table.bin
0x10000 build/hello_world.bin
If that is the case then where all configurations like WiFi and other configurations are stored in the case of ESP32C2 Chip and Modules?

Hello ESP_Sprite,ESP_Sprite wrote: ↑Fri May 24, 2024 7:00 amIn the NVS partition you defined. That's not different for other ESP32 chips.
Below locations are correct because earlier for other ESP32 targets we are flashing bootloader into 0x1000 locations while here it shows 0x0 location for bootloader
0x0 build/bootloader/bootloader.bin
0x8000 build/partition_table/partition-table.bin
0x10000 build/hello_world.bin
Can you please confirm for the same?
We are using 2MB Flash ESP8684-WROOM-05 Module as our end.

Re: Looking support and help to start ESP8684-WROOM-05 Module Development
Hello ESP_Sprite,
We are facing one critical issues like getting garbage data over UART debug console with default UART.
We have also tried to change debug console from menuconfig but results are same like getting garbage data over UART console. We have also checked different baudrate and console settings, but nothing is improved.
Would you please help into it like I am missing anything from hardware side?
Let me know if need anything else from my end.

Potentially something is wrong with the clock configuration. The C2 modules have a 26 or 40MHz crystal, and you need to indicate which you're using in menuconfig.

Thanks for your prompt response.
I have checked into ESP32 Flash Download Tool in which 26 MHz has been detected into chip information and I have changed into menuconfig from 40 MHz to 26 MHz but still no improvement after flashing updated firmware.
(Top) → Component config → Hardware Settings → Main XTAL Config → Main XTAL frequency
(X) 26 MHz
( ) 40 MHz
Let me know if any other change or configuration is required to change to resolve that issue. If anything from hardware end then also let me know.

Hello ESP_Sprite,
Please find following snippet of Flash Download Tool as well for your reference perspective.
So, It shows that 2M Quad Flash Memory with 26 MHz XTAL Frequency.
