Hi,
when I use example spi_slave example, receiver part I have strange behavior:
1. if I take the code as is I get spi_slave: spi_slave_queue_trans(340): rxdata not in DMA-capable memory or not WORD aligned
2. if I use DMA_ATTR and global buffers for spi_slave_transmit(HSPI_HOST, &t, portMAX_DELAY ...

thanks for replies
we would like to :
1.put ESP32 to light sleep
2. transfer data to psram from FPGA (quad spi 200 Mbit/sec, 0.1sec).
3. switch FPGA off, (saves a lot of battery time life)
4. then transfer the data from PSRAM over WiFi (TCP, 2sec)
we did not success yet, on logic analizer we see ...

Hi all,
I have 2 questions, may be you can help me
1. when I connect TDK using jumper, PSRAM does not work, if TDK is not connected it does work, but obviously I cannot use debugger which I need, is there solution?
2.I am new to ESP32 and we want to test next design : write 2.5Mbytes to the PSRAM ...
