Hello, colleagues!
I'm currently dealing with an issue while repairing a Concord Infinity elevator. The microcontroller P87C51SBPN used in the control board has failed, and I need the original firmware dump in .bin format to replace it with a new processor.
What I've done so far:
• Diagnosed the issue and confirmed the microcontroller is the root cause of the problem.
• The original processor is beyond repair, and I wasn't able to extract the dump.
• Reached out to the manufacturer (Savaria/Concord), but I haven't received a response yet.
My questions:
1. Does anyone have a firmware dump for the P87C51SBPN used in the Concord Infinity elevator?
2. Are there any resources or suppliers where I could obtain this firmware?
3. If someone has a working processor, would it be possible to read the firmware from it?
I'd greatly appreciate any help, suggestions, or links. I'm open to discussing further details if needed.
Technical details: zz0.ybtqoonvql9zz
• Elevator model: Concord Infinity.
• Microcontroller: Philips/NXP P87C51SBPN (8051 family).
• The firmware is required for the elevator's control board.
Thank you in advance for your assistance!
AI: Could you specify the version or revision of the firmware you need for the P87C51SBPN microcontroller?
MFW 479
REV .1.0
AI: Have you tried sourcing the firmware from any other channels or communities, such as online forums or technical groups?
yes
