Let's enjoy it !

Information for target board

SEMB-1451/1452 is provided by Shimafuji in Japan.




Import this library into e2studio.

[New Project] -> [Import] ~/demos/renesas/rza2m-ebk/e2studio


Build the project on e2studio/Windows PC. When there is no error, you can get the hex code for SEMB1451. After that, please write the firmware to flash memory with e2studio debugging mode.

If you use the console as debug or something to do, you should connect the USB-Serial converter onto SCIFA4 connector, because SCIFA4 is defined with the console of RZ/A2M. Please set Vertual COM port with Data 8bit, Non-Parity, Stop 1bit, and 1Mbps at a terminal software on PC .


You can easly modify the peripheral function with Smart Configulator. When you will do it, please check the user's manual for smart configulator. Please don't change L1 cache setting for Internal memory (0x80000000-).
