Re: BBPLL Calibration never finishes in second stage bootloader in RTC Configuration

Hi tchapin, We can't reproduce this issue from our side... I have two more questions, 1. What's the normal temperature (which can reproduce the issue) you are testing under? and after heated 30 degree, what's the working temperature. 2. Could you provide the MAC address of your module? Is it modifie...

Re: BBPLL Calibration never finishes in second stage bootloader in RTC Configuration

Hi tchapin, Thanks for reporting this issue. Could you provide more details about this issue? 1. On which IDF version you are experiencing this issue? 2. Is this happening on all ESP32-S3-WROOM-1 modules you have? or only one or two of them? btw, about that patch we have just provided, https://githu...

Re: SPI DMA

Hello, when enabling Async memcpy API: async_memcpy_config_t config = ASYNC_MEMCPY_DEFAULT_CONFIG(); async_memcpy_t driver = NULL; ESP_ERROR_CHECK(esp_async_memcpy_install(&config, &driver)); then SPI with DMA stop working (send garbage). Hi illglu, I think this is because of a hardware limitation:...

Re: ESP32-S3 SPICLK_DIFF Enable

Hi especiallyconfused, There is a register SPI_MEM_SPI_FMEM_CLK_DIFF_EN. When this is enabled, the DIFF clock will be enabled. After that, you need to switch the IOMUX of GPIO 47 and 48 by `PIN_FUNC_SELECT(IO_MUX_GPIO47_REG, FUNC_SPICLK_P_SPICLK_DIFF);`, etc. btw, maybe you need to do this when the ...

Re: how to bme280 spi read?

When using full duplex mode, the rxlength should also include the length of MOSI.

Now the first byte received is supposed to be the MISO while you are sending reg_addr.

Please try increase the len and receive buffer size and see if the hardware starts receiving data from 2nd byte.

Developing with ESP-IDF under WSL2

# Background The support for MSYS2 has been removed (since IDFv5.0?). Now the offically supported ways of developing are: - Command prompt - Powershell But those Windows users used to to work on with MSYS2 (shell commands) may feel bad with the two approaches above. This article describe one approac...

Re: Problem Using SPI Slave Mode With DMA (IDFGH-7468)

If I understand wrongly, you are using another host, to access the flash or ESP32 slave alternatively... Could you check if you have connected ground of three boards together correctly? And maybe we need the logic analyzer capture on the 4 pins of ESP32 SPI interface to check what's happening.. Mich...

Re: Problem Using SPI Slave Mode With DMA (IDFGH-7468)

Hi @berlinetta, Firstly I would like to ask... Are you trying to let SPI flash driver and SPI slave driver taking turns using the same VSPI peripheral? If so, I'm supurised the driver you are using didn't complain about anything.. Michael Hello All, I have been attempting to get the ESP32 to functio...

Re: ESP32S3无法启动 D (188) bootloader_flash:

Hi metoo0713,

我有几个问题:
1. 无法执行的情况,在整板掉电复位之后是否能恢复?
2. 无法执行的情况,能否给我们提供一下flash status的数值:调用 `esptool.py read_flash_status`
3. (先做完以上两步) 如果重新烧写整个固件,问题是否会消失?
4. 问题是否和开发板/模组强相关,也就是说,如果执行了(2)的步骤,出现过问题的板子是否还会再出现同样的问题?

谢谢!
Michael
