If you used a RAM segment of 0xFFFF0000 to 0xFFFFBFFFF then you will only see them referenced in code... Ah. Thanks.

Sorry to raise this thread from the dead, but I think I have something to contribute that could be useful.
I modified dschultz's sh3.cfg to add definitions for memory areas and interrupt vectors, for SH7055 targets.
The "memory area" isn't working as well as I hoped, you still have to manually enter the ROM and RAM section extents when loading a ROM.
I also added a version of the SH7055 device (called sh7055_twinVT) which is useful at least for some Nissan QR25DE ECUs.
They have an incomplete interrupt vector table at 0x000000000 , and the power-on reset code (@ 0x00104) then modifies the vbr register to point to a secondary vector table at 0x00001000.
If someone wants to do the same thing for SH7058 / other devices, the best way I've found is to use the .h and .c files from Renesas which contain the interrupt names (but not the addresses), then work some magic with sed. I actually used Octave, sed, and paste.
The attachment contains only my additions; they need to be pasted in dschultz's sh3.cfg.

Are there the register definition for the SH7059 & SH72543R for use with IDA?

Forgot to mention it here; I copied dschultz' defs and added some Nissan variants to them: https://github.com/fenugrec/nissutils/t ... elpers/cfgIf someone else wants to contribute, I'm missing defs for: 7059 72531 72533 72534

Another Ultra Newb here with another necropost. I'm quite confused... Dropping the sh3.cfg file into IDA's cfg directory doesn't add anything to the list of processors. Am I missing something?  Code: C:\Program Files (x86)\IDA Free\cfg\sh3.cfg

I don't think that version of IDA supports this processor. You need to buy the Pro version.

Good afternoon. Please tell me which processor to choose when opening the firmware in IDA? SH2A, SH3B ... SH4? I have SH7058, it's SH2E, but it's not on the IDA list.

Check the spreadsheet in the first post if you are not sure.
Only IDA Pro supports this processor.

I have IDA Pro. I placed the sh3.cfg file in the cfg folder. When opening the firmware, I select Renesas SH2A, then 7058. Analysis gives a lot of code. If I select SH3 or SH4 when opening the firmware, then I select 7058, the analysis gives little code. What's the difference when choosing SH2A or SH3, SH4?

Choose SH4B, then SH7058.

Are there the register definition for the SH7459 for use with IDA?
Witch used in Imprez's ECU.
