Dear friends , hello to all :)
i need your knowledge about R5F6411FNLG processor.
My problem is my cameras firmware update failed and i bricked a lens olympus 12mm
and olympus software not dedects lens no more and no way to use olympus software.
i checked inside mcu is R5F6411FNLG , i have segger jtag but this mcu is not in list.
camera pinout is attached and i have firmware file.
How can i programme this file to my lens back?OL103011.rar
Flash programming of R32C/111 is described in the device hardware user's manual (chapter 25).
Programming is done via UART1. The connections of the lens don't indicate which UART is being used.
İ checked pdf but its so much detailed for me, if this port not have ueat how olympus can make firmwsre update ?
if u help me i can desolder chip and find pins for programme. I have bga machine . And as programmer upa , xprog, segger jtag, elnec bee prog. Also i have rs232 and lpt ports at my computer.
i need only which pins i have to find , and which software and hardware i have to use.
Thank you so much for all info already
The hardware user's manual I mentioned earlier says exactly which pins to use for serial mode programming.
Elnec do not have an adapter for R32C/111 in LGA package. They support it only in QFP.
From Segger only Flasher 5 supports programming of R32C in serial mode.
You can build an own adapter so you can use the PC UART and don't need a programmer hardware. Use Standard Serial Mode 2, which is using UART. Place a MAX232 or similar between the PC UART and R32C to adjust the signal levels. A long time ago there was a Mitsubishi MF-TenNine cable as adapter. I attach the circuit diagram for it.
As software you should use Renesas FDT. This incudes support for R32C.

i desoldered mcu today , problem is at datasheet there are so many rxd txd pins
(0- to 8)
which pins i have to use ?
another question my xtal connected pins A5 and B6.
Gnd pins D1,D2,D3,D4,D5,C5,E5,F5,G5,H5,J5,K5
Vcc pins C1 ,C2
C2 is vdc1 but none of my gnd pins are declared as Vss at datasheet pinout.AS i und i have to use rxd1 and txd1 .Because u said me its using uart uart1. Am i right?
And when i open my dump with renesas programming software it shows all FF why ?
