- Sun Jun 05, 2022 2:52 am #94699 Hi,

I have a Iduino ESP 13 (with an ESP 8266 chip).
I'd like to upgrade the original AT firmware to the last provided by ESP-IDF (at that time ESP8266-AT-V2.2.1.0).

Uploading the firmware works fine with this command line :

Code: Select allesptool --chip auto --port COM4 --baud 115200 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_freq 40m --flash_size 2MB 0x8000 partition_table/partition-table.bin 0x9000 ota_data_initial.bin 0x0 bootloader/bootloader.bin 0x10000 esp-at.bin 0xF0000 at_customize.bin 0xFC000 customized_partitions/client_ca.bin 0x106000 customized_partitions/mqtt_key.bin 0x104000 customized_partitions/mqtt_cert.bin 0x108000 customized_partitions/mqtt_ca.bin 0xF1000 customized_partitions/factory_param.bin 0xF8000 customized_partitions/client_cert.bin 0xFA000 customized_partitions/client_key.bin

I get the arguments from the documentation and download.config file from the firmware.

But after starting the device, I cannot access to AT command on Serial with 115200 baud. After changing my console to 78440 bauds I can see some errors :

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,7)

Could someone tell me what I'm doing wrong ?
