c3d9eafe60 Modified the linux test bench to take a new parameter which can run simulation from 470M out to login prompt. This shouldn't break the regression test or checkpointing. 2022-04-10 13:27:54 -05:00

2294cbc1c6 Possible fix for trap concurent with xret. Fixes the priority so trap has higher priority than either sret or mret. Previous code had priority to xret in the trap logic and privilege logic, but not the csrsr logic. This caused partial execution of the instruction. 2022-04-07 16:56:28 -05:00

0806d1a134 Updated the bootloader to use the flash card divider. This will allow wally to run at a faster speed than flash. 2022-04-04 10:38:37 -05:00

d83db2cde5 Fixed the SDC clock divider so it actually can work during reset. This will enable the fpga to operate at a faster clock while the SDC is < 10Mhz. 2022-04-04 09:57:26 -05:00
