Programming issue in Inventek ISM43340 EVB

rajvirzala Jul 7, 2015 12:40 AM

Hi,

I am now using ISM43340-M4G-EVB & programming the same using WICED sdk 3.1.2 through USB-UART port. But, I am facing programming issue( I can see no program error ,success message & reset message in WICED sdk). However, I can't see any output(I tried several codes of leds , uart, etc.). Sometimes it works, many times it doesn't. Also in "Device Manager" I can see both ports i.e. WICED USB Serial port & WICED USB JTAG port.

Previously, I was using ISM43341-USB. However, in that I haven't faced such issue.

I suspect the above issue in ISM43340-M4G-EVB due to one of following:

- Fault in ISM43340-M4G-EVB design

- FTDI chip firmware/ FTDI PC driver.

- PC USB power / PC USB port

Working on Windows 7 64 bit system.

Kindly reply ASAP.

I spoke with the team at Inventek about this and they asked me to confirm with you whether or not the 3.1.2 patch was downloaded: http://www.inventeksys.com/inventekproducts/wifi-products/broadcom-wiced/

I downloaded 3.1.2 patch when I started development on WICED 1 month ago.

Nevertheless, I got the solution for above problem. When I commented following lines in platform.c in function "platform_init_external_devices( )", I am facing problem mentioned in previous post.

   /* Initialise buttons to input by default */
    platform_gpio_init( &platform_gpio_pins[WICED_BUTTON1], INPUT_PULL_UP );
    platform_gpio_init( &platform_gpio_pins[WICED_BUTTON2], INPUT_PULL_UP );

As soon as I uncomment above lines, problem disappears and board works absolutely fine.

What could be reason behind that? Is it compulsory to initialize the two pins as inputs?

Inventek team should try this and find out the reason behind that.

Thanks.

I spoke to the Inventek folks this morning and have asked them to respond.

Note that I also moved the discussion from the main WICED forum into their Inventek-specific forum.

Awaiting response from inventek folks.

Looks like this issue is related to BSP.

Reply ASAP.

The ISM43341-M4G-L44 platform in WICED is based on using our ISM43341-M4G-L44 EVB and not the ISM43340-M4G-EVB.
The WICED buttons may be incorrectly configured in the platform file.

We recommend moving to WICED 3.5.2 where this should be correct.
Here is the link to the patch on our site:
