M32160 or M32170 info

Hi,
I have an aftermarket ECU (HKS F-CON V) that utilises the M32160 (M32160F4UFP) for the earlier variants and M32170 (M32170F3VFP) for the latter variants.

I do have access to the actual firmware image of the M32160, aswell as the hardware (all variants).

But apart from that, I am stuck where to go next in terms of trying to read/write the firmware image from the MCU.

Firmware image is at: http://1jzmerc.com/files/hks-faq/firmware/fcv55.s55

The format of the image is:

Code:

# "packet":
#   AA BB CC *256 bytes* DD 0D 0A
# where:
#   AA - 00 or 53
#   BB - upper  8-bit of 24-bit address
#   CC - middle 8-bit of 24-bit address
#   DD - checksum
#   0D - \r
#   0A - \n

Does this format look familiar or is custom firmware blob format?

I do know the firmware can be upgraded via the serial port (sequence documented on the website), but I am more interested in reading the existing firmware before attempting to upgrade it, just in case I brick it.

If anyone can provide pointers, that'd be great.

BK.

M32170F3VFP maybe read in boot mode thru SIO1 serial port according to Renesas docs.
I suspect that M32160 follows the same way.

Do you really have any ideas\schematics\pin assignment\init sequence to put 32160 into boot mode?
