As far as I know adding the PSRAM into the BOM is not a determined thing. But we always recommend the latest release on the same branch, mainly for those fixes introduced. It's not only for compatibility to future hardware.

Hi gesp32,

Here are the versions that support this PSRAM:

Target Branch Merged Released
release/v5.0 4d78c54 v5.0.9
release/v5.1 c5ccf3d v5.1.7 (target)
release/v5.2 857c712 v5.2.6
release/v5.3 9e58fe0 v5.3.4
release/v5.4 a8e166e v5.4.2
master 847ac1a v5.5

Please be noted that when the supply is ...

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 ...

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 ...

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 ...

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 ...

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.

# 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 ...

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 ...

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..
