 I think the next experiment I will do is try to port the baremetal tests to
 something I can load at `0x8000_0000`

+## 2024-08-26
+
+I implemented a new bootrom as the original large bootrom is not initializing
+the UART. This causes baremetal tests to fail until someone properly initializes
+the UART (namely, OpenSBI). The new bootrom, named RBOOTROM, initializes the
+UART and prints an initial message. It also sets a machine mode trap to catch
+potential errors:
+
+    $ picocom -qb 115200 $FPGACTL_UART
+
+    RBOOTROM v1.0 :^)
+    Jumping to 0x8000_0000...
+
+While the bitstream with the potential fixes for the supervisor interrupts is
+not available, I'll try to automate the testing by creating a pipeline that
+automatically runs the tests in an FPGA.
