Engineers at T8 have documented their initial experience working with the Baikal-U (BE U-1000) microcontroller. The team utilized the EVU-BA-2.3 development board to test the chip, which is based on the RISC-V architecture and features three cores: two CloudBEAR BR-350 and one CloudBEAR BM-310.
The hardware includes 192 KB of SRAM, 256 KB of eFLASH, and 2x16 MB of memory in XIP mode. During the setup process, the developers encountered issues with DFU and USB drivers, eventually opting for UART-based program loading and using the Zadig utility to configure drivers for the debug interface.
To enable hardware breakpoints, the team modified the EVU_BA_2.3.cfg configuration file by adding the gdb breakpoint_override hard command. The setup process involved integrating OpenOCD, GDB, and Visual Studio Code to facilitate the debugging of the microcontroller projects.
The development environment was configured using SDK version 2.3.0, dated July 3, 2026, on a Windows 10 system. The team successfully compiled and executed example projects, including UART printf and GPIO LED blinking, to verify the functionality of the development board.
