In my case, I am using the Arduino environment. There does not appear to be any setting that controls this there. I can see other print statements without any issues, only the exception information only appears to go to the UART interface.

This may be the case. It looks like the static allocation of the table is being placed in instruction memory.

Note that the almost identical code that doesn't use the ee.vld.128.ip instruction works fine. Here is my code: volatile register uint32_t *pItem = (uint32_t *)mRMT_mem_ptr; for (register int i = 0; i < PULSES_PER_FILL/8; i++) { if (mCur < mSize) { register uint32_t tmp1, tmp2, tmp3, tmp4; #if 1 reg...

When I insert the instruction ee.vld.128.ip instruction into my code I get a trap. The address I am passing is correct, it is 16 byte aligned (actually 64 byte aligned) and readable using l32i. This is on an ESP32 S3.

Related to my previous open question about the ee.vld.128.ip instruction failing https://www.esp32.com/viewtopic.php?f=2&t=30121 instruction failing, how do I get the ESP32 S3 to dump out exception information over the USB interface? On the project I'm working on I would much prefer to not have to h...

I am seeing a trap when I use the ee.vld.128.ip instruction on an ESP32 S3. As far as I can tell, the way I'm using it should be fine. The value of a12 before this instruction points to a valid memory location: 0x40378d40. The trap also says that the address being accessed is invalid, though the add...

Hi, I have a custom board that I would like to work with the ADF but in my case I have a single microphone connected to the right channel of I2S bus 0 which uses 32-bits per sample. Although the microphone outputs 24 bits per sample if I use anything other than 32 bits I don't receive any output. I ...

The main things I would like to see are: 1. More on-chip RAM 2. Native USB2 support (so I don't need a USB to UART chip). 3. More GPIO pins. 4. Faster processing, especially acceleration for FFT. Maybe move to Xtensa LX7. 5. Better GPIO support for NeoPixels with DMA support (rather than use the IR ...

Never mind. I had to add a digital DC blocking filter. All is good now.

After adding a DC blocking filter it is working. It sounds like the microphone I am using goes down to DC or at least has some DC offset that needs to be removed.
