And when I try to build the gateware, this is the error it produces: Info: Device utilisation: Info: ICESTORM_LC: 5312/ 5280 100% Info: ICESTORM_RAM: 20/ 30 66% Info: SB_IO: 32/ 96 33% Info: SB_GB: 4/ 8 50% Info: ICESTORM_PLL: 1/ 1 100% Info: SB_WARMBOOT: 1/ 1 100% Info: ICESTORM_DSP: 6/ 8 75% Info: ICESTORM_HFOSC: 0/ 1 0% Info: ICESTORM_LFOSC: 0/ 1 0% Info: SB_I2C: 0/ 2 0% Info: SB_SPI: 1/ 2 50% Info: IO_I3C: 0/ 2 0% Info: SB_LEDDA_IP: 1/ 1 100% Info: SB_RGBA_DRV: 1/ 1 100% Info: ICESTORM_SPRAM: 4/ 4 100%
