STM32F769NI + Murata SN8000 - Problem with high throughput clock.

Anonymous · ‎Mar 21, 2017

Hi,

Its my first post on wiced community.

I'm trying to port WWD driver on STM32F7 series (without full WICED SDK).

My platform is STM32F769NI + Murata SN8000 connected throug 1 BIT SDIO. I use WWD + LWIP from WICED SDK ver. 3.7 + Murata patch for SN8xxx for ver. 3.7.

I try to run example FreeRTOS_LwIP_Scan.c example. At this moment I'm able to compile it.SDIO works with DMA and Interrupts. I pass all init functions with WWD_SUCCED including NVRAM and Firmware download.

But unfortunetly I stuck after core reset on SBSDIO_HT_AVAIL flag (I receive 0x40 status exept 0x80):

WWD_ERROR : "Timeout while waiting for high throughput clock\n"

I took nvram and firmware (43362A2_bin.c) from Murata patch.

Is this tis a problem with firmware files or chip revision?

I found solution for last problem on another topic. I had to increase high speed of sdio clock to 4 MHz and now core is working. Now I have to fix some os issues and everything should works Thanks for help.
