SweetAda on POWER8

By: SweetAda

SweetAda (https://www.sweetada.org) got another step of functionality in the high-side of computing and successfully boots on an (QEMUโ„ข-emulated) PowerPC 64-bit POWER8 (R) platform.

The support is minimal, but it is able to startup from CPU reset and can do output on a terminal console.

Standby for future improvements.

SweetAda on NEORV32

Hi all.

Iโ€™ve created a NEORV32 target platform in SweetAda (GitHub - gabriele-galeotti/SweetAda: Ada-language framework).

NEORV32 (GitHub - stnolting/neorv32: ๐Ÿ–ฅ๏ธ A tiny, customizable and highly extensible MCU-class 32-bit RISC-V soft-core CPU and microcontroller-like SoC written in platform-independent VHDL.) is a RISC-V SoC implementation in VHDL, suited for FPGAs.

The setup is blatantly primitive and runs under simulation by means of GHDL, outputting a welcome message inside the simulated UART console. This setup is still WIP, I have to properly integrate the build
machinery with that of the NEORV32 environment.

So far I have no FPGA hardware (besides the time) ready to create a real implementation, so if someone is using NEORV32 on real hardware, and is willing to test, this will be very interesting. Just a OK/KO flag. The current setup needs only UART clocking parameters in the CTRL register, which I suppose it depends on the actual clock configuration. In the meantime I will try to develop things inside the simulated GHDL environment.

Best regards,
G
