2007-04-27 02:51:35     Problem with Serial communication onADSP-BF537-EZ-KIT LITE Board

Hi,

 

We are porting the uCLinux onto ADSP-BF537-EZ-KIT LITE Board.

 

There are no drivers/software installed initially when the board is powered up.

 

After we load the U-Boot onto the board using Visual DSP++, the serial communication using HyperTerminal or minicom is not coming up with the Prompt.

 

So should we install the serial port drivers before loading the U-boot and uCLinux?

 

Thanks in advance.

Hi Saritha,

 

You don't have to install serial port drivers.

 

Regards,

Message: 24922    we already have peripheral drivers for the UART ... sounds more like you're just having trouble getting u-boot up and running first

 

please see this page:

uClinux has already been ported to onADSP-BF537-EZ-KIT board? Why do you want to do it again?

 

What is the chip version on your board? uboot and uClinux can only boot on bf537 version 0.2 and above.

Hi Mike,

 

We are following the steps mentioned in the page and loaded the U-boot using Visual DSP++:

 

  docs.blackfin.uclinux.org/doku.php?id=loading_u-boot

 

But after the U-boot is laoded, when we open Hyprterminal or minicom, we are not getting the prompt.

 

Please help, if we have to make any Jumper/Swictch changes on the board.

 

Thanks in advance

 

Saritha

Message: 24964    probably means you dont have the bootmode selected correctly

 

please refer to this page:

I was messing with this problem since almost 3 weeks. I have a BF533-ezkit. What I figure out is that set the boot mode switch 11, both to ON, such that it boots from external memory.

Then use a binary u-boot file from the u-boot files section, specific to your 537 ezkit board. Program the flash using VDSP with this binary image. Then try rebooting your kit, setting console to regular 57600 8N1 no flow control and u should see u-boot prompt.

 

I am not sure if you might get stuck with some other problem, but this works for me.

 

Thanks

1. Check if the cable is OK.

2. Check if the boot mode is correct.

3. Check if your terminal is set correctly, which is 57600,N,1.

Hi Bhuvanesh,

 

Thanks for the response.

 

We are using the BF537-EZ-KIT  and the bin's avaliable in the   blackfin.uclinux.org/gf/project/u-boot/frs site contain the binary for BF537-Stamp board.

 

So could u pls let us know, if we can use the same binary file for BF537-EZ-KIT  also?

 

Thanks in advance

 

Saritha

I am not sure if stamp version of binary would work on EZ-kit but you can give it a try.

or try compiling u-boot and create a binary to download to the target board.

Message: 25086    the BF537 stamp and ezkit have the same pcb; you can use the same u-boot/linux images on them
