| built from |
| [revision 9b6ea045f9b539b0f708d71962716e5dde865181](https://github.com/cliffordwolf/picorv32/commit/9b6ea045f9b539b0f708d71962716e5dde865181) |

| It has been modified so it does not require external SPI flash. Instead, the program is stored in ROM which is implemented in the FPGA. |
| |
| The ROM content is stored in `progmem.v` file. The file is generated from using the `hex2progmem.py` Python script from a HEX file. |
| |
| **! WARNING !** This version of PicoRV32 does not work with compressed instruction set! Make sure to set up proper architecture when building the firmware. |
| |
| #### Expected output |
| |
| The current firmware produces the following output on the basys3 platform. You should experience similar behavior of LEDs and identical serial output on other boards. |
| |
| - First four leds (LD0, LD1, LD2, LD3) blinking at a regular rate from left to right. |
| - An UART output looking as follows (baud rate must be set to 115200): |
