256Byte</P><P>Hi All,</P><P>I using the imx_usb_loader application to write the image via the SDP "WRITE_FILE" API.</P><P>The image size is&nbsp;0x1ff00 and the load address is 0x100.<BR />I have configured the board to boot from USB and using the default flexRAM configuration:<BR />(128KB ITC: 0x0-&gt;0x20000).</P><P>in "imx_usb_loader" we can control the size of the SDP REPORT2 packet size we transmit (In the SPEC the size is limited to 1024Byte).</P><P>when i try to use the maximum size of 1024Byte, the bootrom is crashing on the last chunk (0x1fc00 -&gt; 0x1ff00), i can see that the USB bootrom device is enumerated and assigned with new address on my local laptop (which is connected to the EVK).</P><P><STRONG>is there a limitation (known bug) that using packet size greater than 256Byte when writing a file of&nbsp;0x1ff00 size?</STRONG></P><P>### logs (with 1024 packet size - FAILURE)<BR />my configuration file:</P><P>&nbsp;</P><P>&nbsp;</P><LI-CODE

using packets &gt; 256Byte</P><P>Hi All,</P><P>I using the imx_usb_loader application to write the image via the SDP "WRITE_FILE" API.</P><P>The image size is&nbsp;0x1ff00 and the load address is 0x100.<BR />I have configured the board to boot from USB and using the default flexRAM configuration:<BR />(128KB ITC: 0x0-&gt;0x20000).</P><P>in "imx_usb_loader" we can control the size of the SDP REPORT2 packet size we transmit (In the SPEC the size is limited to 1024Byte).</P><P>when i try to use the maximum size of 1024Byte, the bootrom is crashing on the last chunk (0x1fc00 -&gt; 0x1ff00), i can see that the USB bootrom device is enumerated and assigned with new address on my local laptop (which is connected to the EVK).</P><P><STRONG>is there a limitation (known bug) that using packet size greater than 256Byte when writing a file of&nbsp;0x1ff00 size?</STRONG></P><P>### logs (with 1024 packet size - FAILURE)<BR />my configuration file:</P><P>&nbsp;</P><P>&nbsp;</P><LI-CODE
