SiFive UART Driver. -2. SiFive PRCI Driver for clock. -3. Cadence MACB ethernet driver for networking support. - -TODO: -1. U-Boot expects the serial console device entry to be present under /chosen - DT node. Example: - chosen { - stdout-path = "/soc/serial@10010000:115200"; - }; - - Without a serial console U-Boot will panic. - -Building -======== -1. Add the RISC-V toolchain to your PATH. -2.

We need to compile OpenSBI with below command: -make PLATFORM=sifive/fu540 FW_PAYLOAD_PATH=<path to u-boot.bin> FW_PAYLOAD_FDT_PATH=<path to hifive-unleashed-a00.dtb from Linux> -(Note: Prefer hifive-unleashed-a00.dtb from Linux-5.3 or higher) -(Note: Linux-5.2 is also fine but it does not have ethernet DT node) - -More detailed description of steps required to build FW_PAYLOAD firmware -is beyond the scope of this document. Please refer OpenSBI documenation. -(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git) - -Once the prior stage firmware/bootloader binary is generated, it should be -copied to the first partition of the sdcard. - -sudo dd if=<prior_stage_firmware_binary> of=/dev/disk2s1 bs=1024 - -Booting -======= -Once you plugin the sdcard and power up, you should see the U-Boot prompt. - -Sample boot log from HiFive Unleashed board -=========================================== -U-Boot 2019.07-rc4-00013-g1837f893b0 (Jun 20 2019 - 11:08:48 +0530) - -CPU: rv64imafdc -Model: SiFive HiFive Unleashed A00 -DRAM: 8 GiB -In: serial@10010000 -Out: serial@10010000 -Err: serial@10010000 -Net: eth0: ethernet@10090000 -Hit any key to stop autoboot: 0 -=> version -U-Boot 2019.07-rc4-00013-g1837f893b0 (Jun 20 2019 - 11:08:48 +0530) - -riscv64-linux-gcc.br_real (Buildroot 2018.11-rc2-00003-ga0787e9) 8.2.0 -GNU ld (GNU Binutils) 2.31.1 -=> -=============================================================================== - -Now you can configure your networking, tftp server and use tftp boot method to -load uImage. - -========================================================================== -=> setenv ipaddr 10.206.5.241 -=> setenv netmask 255.255.252.0 -=> setenv serverip 10.206.4.143 -=> setenv gateway 10.206.4.1 -=> tftpboot ${kernel_addr_r} /sifive/fu540/uImage -ethernet@10090000: PHY present at 0 -ethernet@10090000: Starting autonegotiation... -ethernet@10090000: Autonegotiation complete -ethernet@10090000: link up, 1000Mbps full-duplex (lpa: 0x7c00) -Using ethernet@10090000 device -TFTP from server 10.206.4.143; our IP address is 10.206.5.241 -Filename '/sifive/fu540/uImage'. -Load address: 0x80600000 -Loading: ################################################################# - ################################################################# - ################################################################# - ################################################################# - ################################################################# - ################################################################# - ################################################################# - ################################################################# - ################################################################# - ######################################## - 1.5 MiB/s -done -Bytes transferred = 9162364 (8bce7c hex) -=> tftpboot ${ramdisk_addr_r} /sifive/fu540/uRamdisk -ethernet@10090000: PHY present at 0 -ethernet@10090000: Starting autonegotiation... -ethernet@10090000: Autonegotiation complete -ethernet@10090000: link up, 1000Mbps full-duplex (lpa: 0x7c00) -Using ethernet@10090000 device -TFTP from server 10.206.4.143; our IP address is 10.206.5.241 -Filename '/sifive/fu540/uRamdisk'. -Load address: 0x82500000 -Loading: ################################################################# - ################################################################# - ################################## - 448.2 KiB/s -done -Bytes transferred = 2398272 (249840 hex) -=> setenv bootargs "root=/dev/ram rw console=ttySIF0 earlycon=sbi" -=> bootm ${kernel_addr_r} ${ramdisk_addr_r} ${fdtcontroladdr} -## Booting kernel from Legacy Image at 80600000 ... - Image Name: Linux - Image Type: RISC-V Linux Kernel Image (uncompressed) - Data Size: 9162300 Bytes = 8.7 MiB - Load Address: 80200000 - Entry Point: 80200000 - Verifying Checksum ...
