imx27 board using atk tools program image issue

Question asked by Zhang Jay on Aug 6, 2013

Dear all,

 

I have 2 boards, one is the imx27ads boards and another is designed by ourselves, on our own board , when I program the image file into board's flash, get the error:

Can not execute RAM Kernel

 

I check the atk tool source, I find when execute the Bootstrap End Indication Operation, I got the error response(0x88888808), 0x88888888 is correct.

After that I compare the 2 boards log(listen to PC serial port write/read), got the log(refer to the attachment files), I find the first difference is when execute the download command, as below

from the imx27ads board I got:

04 04 A0 00 40 00 00 00 00 BC C0 00 00 00 00 00

from our board I got:

04 04 A0 00 40 00 00 00 00 2F 30 00 00 00 00 00

I have program the same image file

All is the same but the Number of byte to be written in Hex,  I don't know why on our board the size is so small.


In code, the size is desided here:

gui_application/FlashToolDlg.cpp:


    // open image file   fp = fopen(m_strImageName, "rb");   if (!fp)   {   InsertLog(CString("Can not open image file:") + m_strImageName);   return FALSE;   }   // get file size   if (stat(m_strImageName, &fstat) != 0)   {   InsertLog(CString("Can not open image file:") + m_strImageName);   fclose(fp);   return FALSE;   }   size = fstat.st_size;   buffer = new unsigned char[size];   // read image file data to buffer   fread(buffer, 1, size, fp);   fclose(fp);

 

Why I program the same image file but I got the different size of file?
