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 the...

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, u...
