Short some magic pins to start X-Modem sequence in MCU boot code(E112 and 3.3V for PCB 13xx, 1335 for example). The number is etched on PCB as 2060-701335-xxx 4. Select correct ROM image file and flash it to the drive with the program. Program will use special loaders (called EraseL.dll, SystemL.dll) to do so 5. Per my understanding, provided utility supports only 128KB flash files (external flash chips). For 192KB flash the program will look for Erase.dll and System.dll files that are not provided, thus will not work with those. I have doubts that the code posted here will work. I had a look inside the "spice9ray"-ed code of this Utility. (assuming that the c# I saw it's close to it's origins) When it builds the header for the data to be sent to the xmodem...it gets the memory_address (offset 16 in the header...where to copy the code) form the rom.bin..and patch the eraseL header. in this way...the bootstrap's terminal code..will "map" the code from "eraseL" at the location where it should be the firmware's "kernel loader" mapped...but instead...it executes an entry point for this injected module...which doesn't exist (FFE1F299). Beside..the EraseL code has many branches to nonexistent functions which points inside the bootstrap's code (ie. for my pcb 128k rom 2060-701336-003 REV A) Doesn't fit in my "terminal researches" Code: i1 = System.BitConverter.ToInt32(arrbyt, 16);//arrbyt holds flash_to_upload.bin
i2 = 0; while ((i2 < 4))//patch eraseL.bin at the same location { arrbyt1[16 + i2] = (byte)(i1 >> ((i2 * 8) & 31)); arrbyt1[20 + i2] = arrbyt1[16 + i2]; i2++; } arrbyt1[20] += 1;//the entryPoint to be called by the Bootstrap after injection points nowhere...FFE1F299+1 (or somwhere inside a working firmware's erase function) |

I have laughed my butt off how that tiny terminal code converts hex digits to binary and vica versa... they are braindead at marvel... |

Seems to be a good solution for bricked PCB. Need to try it and see. |
