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 ?
Please see chapter 25.4 for flash programming in serial mode, table 25.21 for pin connections.
Chrystal is connected to E1-F2.Vss is on F3 and E8.CNVss on D2 must be pulled up.
I hope I marked all relevant pins.
I don't see what you mean on the pinterest page but it is probably OK.
i made wrong alignment about chip pins.now i corrected and it seems my xtal location is ok.
i dedected pins.
i will put mcu back and report u .
But u didnt answer my question about renesas programming software.
when i load my file it shows all FF :(
Can u please mark to me rx and tx pins from picture :(
Because im very confused about pinout :(
Left down side is dot of mcu also xtal position is clear at pic down.
Thank you already
