I am trying to program RL78/G12 R5F1068 MCU using this programmer but facing problems. Whenever I connect the EZ-Cube programmer to PC(Windows 7) Windows displays message that USB driver not installed,and my MCU is not detected in PC. I tried searching for drivers of this programmer but didn't found any.
Any help would be appreciated.
Hi MVA, You can download the driver "ez_cube_driver.zip" from the link below. www.renesas.com/.../D3003098.html But it's Chinese, Can you do that?
Hi Kirin, yesterday I installed drivers and now EZ-cube is detected in Windows. But now my MCU is not detected Communication failure is reported.
EZ-CUBE has different firmware depending on the connection target CPU. Check your EZ-CUBE's firmware below flow.
You can download the firmware tool from the Chinese site, too. https://www.renesas.com/zh-cn/software/D3015141.html
1st, Overwriting the firmware of EZ-CUBE to "RL78_OCD_FW(except G10).hex" for RL78/G12.
2nd, Disconnect and plug in the USB cable after writing the firmware into EZ-CUBE.
3rd, Restart GUI QB-EZUTL, then click button "F/W Ver." and check the F/W version "RL78 OCD F/W" or not.
4th, Make sure the circuit composition shown in Figure 3-2(20pin,24pin) or Figure 3-3(30pin) according to the pin number of G12.
