error target connection to i.MX35 in Visual Studio 2005

Dear Community,


i have a problem with the connection to the i.MX35 board in boot mode.

error: the visual studio 2005 (Win CE 6.0) refuses the connection to i.MX35
in boot mode.

In the ethernet download settings, no target device boot name and no active
target device is visible.
Settings for Kernel device map are
Target device: CE Device
Download: Ethernet
Transport: Ethernet
Debugger: Kdstub

In the nand boot mode, the board starts with the bootloader and the ce ethernet
bootloader 1.0 from the nand flash. I configured the boot to stay longer in the delay
and set the ip address to 192.168.3.11.

In the delay, image launch from flash or enter boot option menu is possible.

But i can not download software, as the visual studio does not recognize the
i.MX35 Freescale board. When i start putty, i always see the infos form the
bootloader, then the counter counting down the seconds untill booting the image
form flash.

So what is wrong, that visual studio does not recognize the board?

I tried to flash the XLDR or eboot with the ATK to  the nand flash, but there
was always an connection error.

I set the boot options for the SD-Card and i was able to flash the XLDR and eboot.
But setting the boot options for the SD card, visual studio also does not
recognize the board.

I think i tried all the combinations which are possible. Hyperteminal COM connection

with putty works well, but the Connection to visual Studio plattforem builder does not.

Now my question is, is there anyone who can help me? Did anyone a software
download with the visual studio 2005 and the ATK to the nand flash?

I thought, the board was in boot mode. What does the board transmit in boot mode?

Regards,

Alex

  To connect the i.MX35 target board with host VS 2005, please follow
section 5.4 (Configuring Ethernet Connection for Download and Debug) 
of "pdk2009_12_imx35_WinCE60_UG.pdf".


Have a great day,
Yuri

Hi Yuri,

thanks for reply.

i thought i flashed the eboot and xldr to the sd card with ATK. But when i boot from the nand, there

comes clear text in the serial putty window counting down the delay. In this delay time

i am able to switch to the soc menu, where i perhaps configure the boot delay time

and the ip address of the board.

When i boot from the sd card, there is different output in the same serial putty

window. There are only not readable characters.

So my first question is, how does the eboot message look like? After i can say

clearly my board sends the eboot message, then i can move to the problem

with the ethernet Connection in Visual Studio.

Firewall is no Problem, as i Flash another embedded board.

Regards,

Alex

  The fact of non-readable chars on console means, that UART speed is not correct.

Please check clock initialization.

Hi Yuri,

yes, i also think so. I tried some speeds in the past on the COM Interface in the Windows system settings,

but no speed sees to be correct. (e.g. 9600, ..., actual 115200 i think. At 115200, i get the SOC menu)

Can you please send me the correct speed for the serial connection to receive the bootme messages.

Regards,

Alex.

I meant UART speed of the i.MX35 based target, which is configured by
WinCE. Information about WinCE initialization files (startup.s, xlds.s)

may be found in the next app notes for i.MX51 (having the same WinCE
structure as for i.MX35 BSP).
