Before going to a custom PCB, have you got this working on a development/evaluation board?

It's always good to start from a known-good system - then, when your custom hardware doesn't work, you can compare & contrast the known-good system.

Are you sure you have the correct SPI Mode?

The trouble with SPI - unlike, say, I2C - is that it has no official definition.

So, while is probably safe to assume that Atmel's meaning of "SPI mode 0" is the same as ST's meaning of "SPI mode 0" - that is not guaranteed...

See: https://www.avrfreaks.net/comment...

And, similarly, you're sure that Atmel's meanings of "CPOL" and "CHPA" are the same as ST's ?

Again, having a known-good reference system would help ...

As rev says, the support for this product is, shall we say, "not fully mature" - even on Atmel's own processors.

And the support does seem to rely upon ASF - which is no help to you.

So, unless you have some really solid direct FAE support on this (which doesn't seem to be the case?), I think you may be in for an uphill struggle ...

Hello Harwinder ..

can you please share how to use winc1500 with any other MCU? I mean without using the API.

Thanks

Hello Harwinder,

Thank you for the project. Please can you send me the détails of the STM32F4 pins used for WINC1500 (INT, SPI, Chip Enable, ...)  on this project

Best regards,

Thankyou. But in your project you are using PA1 PA2 PA3 PE3 PA4 in main.c and PA5 6 7 for spi. Have you a version uptodate ? Thx

In fact, I found the use of the PAxx also in the code 

void nm_bsp_reset(void)
{
    HAL_GPIO_WritePin(GPIOA,CONF_WINC_PIN_CHIP_ENABLE,GPIO_PIN_RESET);
    HAL_GPIO_WritePin(GPIOA,CONF_WINC_PIN_RESET,GPIO_PIN_RESET);
    nm_bsp_sleep(100);
    HAL_GPIO_WritePin(GPIOA,CONF_WINC_PIN_CHIP_ENABLE,GPIO_PIN_SET);
    nm_bsp_sleep(10);
    HAL_GPIO_WritePin(GPIOA,CONF_WINC_PIN_RESET,GPIO_PIN_SET);
    nm_bsp_sleep(10);

Can you share us an uptodate version please ?

Thank you

Thank you,

I Have tested the pinout, the initialization is sussessful but the execution is bloqued on the function wait_for_bootrom :

 while(1) {
  reg = nm_read_reg(0x1014); / wait for efuse loading done /
  if (reg & 0x80000000) {
   break;
  }

What mean ?

thank you

Now I have this Debug message 

HELLO....(APP)(INFO)Chip ID fff5ffff
main: m2m_wifi_init call error!(-5)

I use a STM32F407 Discovery board

Why in the beginning of the main, you putted PE3 and PA4 on high level ?

Thank you,

here is a picture of the board STM32F4 Discovery connected to the WINC1500-X-Plained and the used pinout 

Thank you

which VBAT ? on board or Winc ?

Sorry, I dont find a VBAT pin on the WINC1500 X Plained Kit

Same problem. I obtained on the console the message :

ELLO....se read...(00)(APP)(ERR)[spi_data_read][379][nmi spi]: Failed data response read...(00)
(APP)(ERR)[spi_read_reg][619][nmi spi]: Failed data read...
(APP)(ERR)[spi_data_read][379][nmi spi]: Failed data response read...(00)
(APP)(ERR)[spi_read_reg][619][nmi spi]: Failed data read...
.........

.......

thank you very much! this topic is what I'm looking for,

Do you try this with Xplained module? or just ATWINC1500 with your own schemetic?

If you using Xplained module, where do you connect the ID pin? No connect? or VCC, GND, or another GPIO?

how could you get that message? From uart?

you mean this one?

hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_4;

4 to 256?

Hi everyone,

I am trying to use winc1500 with STM32f429I-disco kit . 

But I am not able to read CHIP id. I am getting error same as above.

"HELLO....(APP)(INFO)Chip ID fff5ffff
main: m2m_wifi_init call error!(-5)"

Does any one help me here?

I have configured following pins for my board.

SPI4 

SCK--> PE2

NSS --> PE4

MISO--> PE5

MOSI --> PE6

Wake --> PF3

IRQ--> PF2

Chip enable --> PF5

Reset --> PF6

I trying to use "Harwinder" 's code for my reference. 

Thanks for your time.

--Regards,

Meet Shah

Hello All,

I have SPI bus error issue in WINC1500 + NUCELO_F429ZI board, It reads the chip ID firmware version correctly. but Write block is failed while sending the connect command. I have connected using the Jumper wires with WINC1500 XPRO board and NUCLEO_F429ZI board.

Please advice on this issue, I stuck here.
