After that, U-Boot was fully functional, and we did not have to wait for a board spin to make any progress. Once we received a newer version of the target board with correctly functioning flash memory, we returned to debugging those parts of U-Boot that we hadn't been able to test earlier. You'll need to wait a moment whilst it analyzes the file. been able to flash the firmware: - Romcode/Initialize DDR/Initialize PLL/USB Control setup error. Navigate to your Downloads folder and select the IMG file that was downloaded previously. USB Burning Tool Error restore firmware - FreakTab. Running U-Boot after loading it into RAM via a JTAG interface (using Codewarrior and the USB TAP) allowed us to continue our U-Boot bring-up tasks, even though we had no functional flash memory. in the USB Burning Tool program, click on the 'File' menu and click 'Import image'. (there are plenty of things that are independent of where the U-Boot image comes from). While the hardware was being redesigned and re-fabricated, we wanted to continue testing/debugging those parts of our U-Boot configuration that did not depend on flash memory, for example, I2C, Ethernet, FPGA configuration, PCIe, etc. In our situation, it was found that early prototype target board hardware included an error in the address bus connection to the flash memory that prevented us from using that flash memory. (There are a few reasons listed in the README, and they all sound pretty reasonable to me, in contrast to some of the other advice available on this subject) In fact, having non-functional flash memory is one reason you might want to debug U-Boot in RAM.

click on the RESET hole behind, while still resting, connect the other end of the USB cable to your PC and connect the power supply while still being supported. This document is pretty terse and leaves many questions unanswered, but I found it a reasonable place to start when I needed to debug U-Boot for a new board, before the flash memory for that board was operating correctly. Click 'File' and choose 'Import image', choose the. They have provided a somewhat useful document about the process in the file $/doc/README.ramboot-ppc8500 (in U-Boot V2010.12).
Someone at Freescale has done this, for their P1022DS evaluation system (and some others as well).
