For this you need to connect MCLR to GND.

Thus, it is safer to do it before attempting a connection to the SPI flash as no current will be accidentally injected! This is very important because flashrom sets the electrical mode of the GPIOs.

Once properly recognized by flashrom, keep the FT232H connected to the USB port.

In the case your the FT232H is not recognized, run the following commands and go to step 2. Note: flashrom can never write if the flash chip isn't found automatically. Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). If your FT232H is properly recognized by flashrom, you should see:įlashrom v1.2 on Linux 4.10.0-38-generic (x86_64)įlashrom is free software, get the source code at

In the Linux terminal launch: flashrom -p ft2232_spi:type=232H.

Make sure the FT232H is recognized by flashrom Alternatively you can also use a breadboard. To be more effective in the process, I suggest you to equip the pins D0 to D3 and GND with this type of probe, it will allow to easily connect it to the flash memory (see next step). Note 2: If you have more than 500 of difference it will throw the RLOD again straight away, thanks Venutech for the feedback! Add test clips to your FT232H Note 1: You could also read the min and max voltages using a CAN interface, see this article: If you have more than 100 of difference between the cells, then you should try to manually balance the pack by individually charging the concerned cells. In my case the cells were well balanced: Cell #

Optional: TC2030-IDC connector, use it to reduce the number of wires to solder from 6 to 4.įollow this video: Check the voltage levels of the cells.

Recommended: Clamp / tool to keep the BMS push button pressed.

Linux computer with flashrom v1.2 installed -> precompiled GNU Linux 圆4 bin here.

Small diameter wire (I used KYNAR WRAPPING WIRE AWG 30).

FT232H interface or equivalent recognized by flashrom, for example: UM232H-B-NC.

This method has been superseeded by the AMNESIA modchip, please consider it! BOM If your cells are way too unbalanced ( >= 500 ), make sure to manually charge/equalize them before clearing the memory. This procedure allows to clear the RLOD error by erasing the content of the SPI flash memory, it worked on B2XR FW v2.1.7 and v2.5.1. Before starting, you must prepare your working area, make sure you can easily move the battery to a safe zone in the case things are really going wrong.ġ1th June 2020: I haven't thoroughly tested the battery after the FIX (it is too early) -> I don't know if there are any potential side effects yet.Ģ2nd June 2020: I recharged the battery 5 times up to 100% and rode 48, so far so good!Ģ8th November 2020: A way better method is available -> AMNESIA modchip Introduction
