I'm using nrf52832 DK with SPI slave mode to read 600 bytes from other nrf52832 DK with SPI master mode but i can't receive more than 255 bytes buffer.
You can find more information about SPI in the documentation. SPI slave device uses DMA. The size of the frames that the packet is divided into is 255 bytes. Each frame is delivered in one bus cycle.
I'm using zephyr OS actually, I devided the rx_buf[600] to arr1[255], arr2 [255], arr3[90] and try to call the spi_read function multiple time but it's only receive 255 first bytes of 600 byte.
