m32r

Based on the document number REJ10J1669, it would appear that FDT does not support the M32R series of devices.  This is likely due to the E8/E8a not supporting these devices.

Target Decives for E8

Target Decives for E8a

Thank you for the information. So is there a tool that will perform the erase mcu procedure?

Have a look at this thread:

I understand that the MCU is obsolete and no longer supported. As a student, I was trying to learn something, and I have access to this MCU. It is a pity that a tool for writing these MCUs is no longer available for learning purposes.I saw material on Youtube where someone was using FDT to write ECU. Hence my question. |What to do if technology is from Poland 20 years back ...
Have a nice day!

JimB, please tell me is it possible to connect to the MCU via the console and issue commands? According to the documentation, Block Erase (H'2020) is responsible for erase?
Table 6.5.2 Commands in Flash E/W Enable Mode
Command Name Issued Command Data
Read Array command H'FFFF
Halfword Program command H'4040
Lock Bit Program command H'7777
Block Erase command H'2020
Clear Status Register command H'5050
Read Lock Bit Status command H'7171
Verify command (Note 1) H'D0D0

I'm sorry I know nothing about these devices, I only have some experience with FDT and I knew where to find the info about which devices were supported, to answer your original question.

Hopefully someone else would be able to help you with device specific questions.

My advice would be if you are looking for hardware to use for educational purposes, to find something more recent.  For something like $25USD you can get a basic Renesas target-board for RX/RL78/RA that would have a full complement of tools available to use.  And I'm sure there a many other non-Renesas type of kits available at similarly low cost.

Thank you for the information provided. I will try to find a flash tool.
