Re: LittleFS: fail to create partition image

Solved. You need to add the littlefs_create_partition_image() command after the line project(yourprojectname) in the main CMakeLists file. If its done before, the compiler doesn't know about the existence of the littlefs_create_partition_image() command yet

LittleFS: fail to create partition image

I'm trying to use the CMakeLists.txt compile command to create and upload the file partition when I run the idf.py build command. I'm using IDF version 5.3.4.

I'm porting my code from using SPIFFS to LittleFS. I'm using joltwallet/littlefs. I've added it as a dependency using idf.py add-dependency ...

Re: Out of buffer: OTA + AWS S3 + presigned URL

Solved. You need to adjust buffer_size_tx, not buffer_size, in esp_http_client_config_t config

Out of buffer: OTA + AWS S3 + presigned URL

I'm trying to implement OTA updates using presigned URLs to access a AWS S3 bucket. The firmware.bin file is stored in S3. I generate a presigned URL with 15 minute expiry. I send the presigned URL to the ESP over MQTT. The payload is as follows:

I (60877) OTA_MQTT: MQTT message received (1008 ...

PCB review

Hi. I am making custom ESP32 boards, but I wish to remove the CP2102 programmer IC from the board for prototyping, because it costs quite a bit to have it on every board. I am making an external programmer. I want this to be as small as possible. I'd appreciate a review of my circuit. I am following ...

Re: USB-C to USB-C not working, USB-C to USB-A working, have pulldowns

There was an oversight on my side. The PCB assembly used 1k ohm resistors instead of 5.1k ohm. I changed the resistors, and it works perfectly now.

While I have your attention, are there any suggestions you have for the layout of my tracks? Is there anything I could do better?

USB-C to USB-C not working, USB-C to USB-A working, have pulldowns

Hi. I have a custom board design that uses USB-C in USB 2.0 mode for data and 5V power. I am aware that in order for a USB-C host to recognise the USB-C peripheral, it requires a 5.1k ohm resistor on both CC1 and CC2. I have placed these resistors on my board. When using a USB-C to USB-A cable, I am ...

Re: ESP32-WROOM-32D does not always reset on power-up

Not on the chip/module datasheet (https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32_datasheet_en.pdf), but on the devboard schematic: https://dl.espressif.com/dl/schematics/esp32_devkitc_v4-sch.pdf.

Re: ESP32-WROOM-32D does not always reset on power-up


Yeah, remove that. Likely it's empty when you boot up and it is only charged by the internal pullup on GPIO0, so there's a high chance the ESP32 comes out of reset and sees GPIO0 low, causing it to boot into download mode rather than start your application.


Thanks for the suggestion. I found a ...
