HULKPROG - REPAIR DATA FILES
Mercedes-Benz 48V lithium battery (W206 C-Class / W223 S-Class)
Preh battery management board with Infineon TC277TP (SAK-TC277TP-64F200S)
Module in HULKPROG:  Module > Benz > "Benz 206-223-48V battery-TC277TP"

These files are the memory content of a WORKING battery module. They are used
to bring back a module that no longer communicates or is locked after a fault.

FILES
  TC277TP_FLASH.bin    4 194 304 bytes   TC277TP program flash  (0xA0000000 - 0xA03FFFFF)
  TC277TP_EEPROM.bin     393 216 bytes   TC277TP data flash      (0xAF000000 - 0xAF05FFFF)
  M95M01_EEPROM.bin      131 072 bytes   external M95M01 SPI EEPROM (8-pin chip next to the MCU)

WHICH FILES FOR WHICH BOARD
  Board WITHOUT an external EEPROM chip : TC277TP_FLASH.bin + TC277TP_EEPROM.bin
  Board WITH an M95M01 EEPROM chip      : M95M01_EEPROM.bin
                                           (and the two TC277TP files if the MCU is also damaged)

HOW TO WRITE THEM WITH HULKPROG
  With an up-to-date HULKPROG software the file loads by itself: select the
  chip (FLASH or EEPROM) and the log says "Data file loaded ... ready to Write".
  With an older software use the Load button and pick the file in this folder.
  0. Connect the board by JTAG (TCK, TMS, TDI, TDO, TRST, PORST, VDD/3.3V, GND):
     click the "Wiring" button of the module, the diagram is on wiring.hulkprog.com.
  1. ALWAYS READ FIRST: select TC277TP-64F200N-DC_FLASH, click Read, then Save.
     Do the same with _EEPROM and _UCB. Keep these original dumps.
  2. Select TC277TP-64F200N-DC_FLASH  -> Load -> TC277TP_FLASH.bin  -> Write -> Verify
  3. Select TC277TP-64F200N-DC_EEPROM -> Load -> TC277TP_EEPROM.bin -> Write -> Verify
  4. M95M01 boards: select Chips > ST > M95series > M95M01-R_EEPROM (or -W / -DW,
     according to the marking on the chip) -> Load -> M95M01_EEPROM.bin -> Write -> Verify
  The UCB (protection) area is not part of these files: do not write the _UCB module.
  After the repair the module may need coding to the car with a diagnostic tool.

The files are installed automatically by "Start HULKPROG.exe" into
<HULKPROG folder>\data\Benz\Benz 206-223-48V battery-TC277TP\
and can also be downloaded from https://www.hulkprog.com/#download

Origin: dump "benz48V-W206-ok" (Intel HEX, 2023-04-21) and "M95M01.bin original",

Use at your own risk; always keep the original dumps of the module you repair.
