Hi,
I flashed an EMW3080B module with this firmware ST-EMW3080B_V2.1.11_SPI.ALL from this location on another board not B-U585I-IOT02A. It is connectet to SPI from STM32. Problem is next: when MCU set pin 11(CHIP_EN) from EMW3080B to HIGH to enable module and set pin 8(CS_SPI) to LOW, module not set pin 13(FLOW) to HIGH and obtain error "flow is low" and after 20 msec timeout "wait flow timeout 0". This result from this code:
mheader.type = SPI_WRITE;
mheader.lenx = ~mheader.len;
MX_WIFI_SPI_CS_LOW();
/* wait EMW to be ready */
if (wait_flow_high(20) != 0)
{
MX_WIFI_SPI_CS_HIGH();
DEBUG_ERROR("wait flow timeout 0\r\n");
return;
}
in file mx_wifi_spi.c. In log from module:
"[1852][mx_spi: spi.c: 253] SPI type is not master write ff"
Why module not working properly? Where is the problem?In firmware?
