SDIO interface on DM6446

2008-07-31 Thread sandeep sheriker










Hi,
    I
am working on  wifi which have a SDIO interface for Davinci DM6446.
The SDIO driver works fine when booted for first time and  after
working for 10-15 minutes, when  I do a hard reset, the SDIO driver
load fails.  while debugging the driver code, the SDIO driver fails to get
response from the  Wifi  chip. however when I probed the SDIO signal
lines at the hardware level and I observe that the frequency of SDIO
clock on the DM6446 is doubled from 24MHz to 48 MHz over certain
temperatures.



Any
help would be appreciate. Thanks.


Regards

UART2 with RTS and CTS Enabled [ problem]

2007-11-19 Thread sandeep sheriker
Hi, 
   
  Iam not able to Transmit and Receive Data from UART2 port with RTS and CTS 
Enabled. 
   
  I have also changed the kernel code  (/arch/arm/mach-davinci/board-evm.c and 
clock.c) and  enable the power of UART2 and to select UART2 and U2FLO  from 
PINMUX1.
  and  enable the AUTOFLOW bit and RTS CTS bit in MCR register.
   
  As per my undersanding 
  Host need to it sends a Ready to Send signal (RTS), and waits for CTS (Clear 
to Send signal) to come back. to check the Satus of CTS i need to Read a MSR 
[Modem Status Register], but i dont find this Register in the UART 
Specification  and also Davinci Technical Refernce manual. 
   
  Is there any other method to Check Status of CTS. please help me out.
   
  Thanks  Regards
  Sandeep S M
