Order No. 834 effect on SBOM

Users of Espressif products are concerned that Order 834 will make it impossible to comply with EU CRA and US Cyber Trust Mark requirements because it will be impossible to verify the source of software components critical to the operation of the device. This law went into effect immediately so ...

Re: ESP32-C5-WROOM-1 Top Layer and 4 layer PCB layout

Thank you but Datasheet Pre-release v0.5 does not show the PCB layout at all so it's unclear.

@LJH Are all these answers correct?

1. Which document is correct?
Datasheet - ignore declaration of this area on dxf
2. For a 4 layer board where layer 2 is solid GND and 7.8 mil away from top, is it ...

ESP32-C5-WROOM-1 Top Layer and 4 layer PCB layout

I need some clarification on PCB design requirement for ESP32-C5-WROOM-1:

In the 2D download: https://www.espressif.com/sites/default/files/modules-dxf/ESP32-C5-WROOM-1%20PCB%20Footprint_0.dxf there is a unusual declared "No GND copper only in top layer"

Yet, in the device datasheet: https://www ...

Re: ESP32 OTA via BLE

It's an old issue, but an obvious need. Here's the closest thing I have found from espressif. But it does not support IoS. Is there more?

Re: ESP32 SPI SCLK GPIO drive strength

I recently tested this on SPI lines to reduce EMI, it appears to work great on an ESP32-S3. Setting 0 might be too extreme depending on your clock rate.


gpio_set_drive_capability((gpio_num_t)brd->GPIO_LCD_CLK, GPIO_DRIVE_CAP_0);

Re: \examples\peripherals\gpio\matrix_keyboard Example not working on S3

True but documentation should replace the role if code.
These are supposed to be examples for most platforms used by newcomers.
This would be much better.
#ifndef CONFIG_IDF_TARGET_ESP32S2
#error This example only supported on ESP32S2
#endif

From what I can tell the S3's dedicated GPIO does not ...

\examples\peripherals\gpio\matrix_keyboard Example not working on S3

I see other topics that the matrix_keyboard example only works for devices with dedicated GPIO. But it seems to only have been tested with the S2, not the S3 which also has dedicated GPIO. Although the S3 does seem to lack this definition: SOC_DEDIC_GPIO_HAS_INTERRUPT

Could this work on on an S3 ...

Re: vscode ESP-IDF Setup error

Deleting both the c:\users\username\esp\esp-idf and c:\mos then restarting the installer again appears to have solved it.

ESP_RF_Test_tool upload error

The lab is scheduled, but the test tool will not upload over serial.
I can only assume it's because it changes the baud rate for upload from what is selected 115200 to 921600 which is more than my FTDI cable can support.

Console:
ESP_MAC: 00:00:00:00:00:00
