it’s something wrong with your environment settings. Suggest to follow the RV32M1_Vega_Develop_Environment_Setup.pdf to set up your Eclipse environment.

Hello VS Eschholz,
The system definition determines the BLE stack run on zero-risky core. So the radio module only is mapped to the memory space of zero-riscy.

Hi,
Any 8-byte writing, even all bytes are set to 0xFF, is a real write operation to the 8-byte a program flash block. As a result, the ‘invisible’ check bit of that program flash block will be updated. Then the next writing will fail because of the updated check bit if having no erasing. The check bit will be reset only in the erase.

Hi Galak,
There’re 4 cores on the chip, but only two cores, one of CM4 and RI5CY, one of CM0+ and Zero-riscy, are recommended because of the two sides feature of Message Unit (MU) module. One side is CM4 or Ri5cy and another side is CM0+ or zero-riscy. In theory, you can use 4 cores together, but MU will only manage two cores. Your software needs…[Read more]

All SRAM and Flash can be accessed by two cores. But Each core accessing to the SRAM/Flash associated with another core has low performance.

Howard Liu replied to the topic Why do we need an external deubgger? in the forum Getting Started Support 5 years, 2 months ago
Main reason is that DAPLINK cannot be used to debug non-arm core according to the license of CMSIS-DAP. And the JTAG support isn’t included in the latest official cmsis-dap implementation.
If someone has a standalone debugger running daplink firmare with JTAG support, he can use it to debug RISC-V core just for try and test by changing the…[Read more]
