Tegra186 (P2771-0000-500) # tftpboot 0x80080000 Waiting for PHY auto negotiation to complete… done You can try to restart all the services: /etc/init.d/rpcbind restart /etc/init.d/nfs restart /etc/init.d/nfslock restart. I shared the console message for your ref to verify, please suggest if anything missing here. Use TFTP to transfer the u-boot image generated earlier. Then restart the standalone service service tftpd-hpa restart and try the connection again. set disable yes in /etc/xinetd.d/tftp and restart xinetd. I tried the instruction as mentioned in the mail and issue remain same.Īlso used the various dtb address to load the u-boot-dtb.bin to ruled out BSP conflict in the u-boot. Seems youre starting tftpd-hpa from xinetd and as a standalone service at the same time. Note that we understand you not wanting to reflash everything for each iteration of your U-Boot code, but you can just flash it with the ‘-k kernel’ (or –k LNX on T210, IIRC) flash.sh command, which would be much quicker. Preparation x Setup TFTP Server for U-Boot We’ll start off with a terminal connected to the board and sitting at the U-Boot prompt. You can try loading your U-Boot binary into RAM 0x80080000 (CONFIG_SYS_TEXT_BASE), loading the DTB from the BSP somewhere else in RAM (that doesn’t conflict with or overwrite U-Boot), and then setting X0 to the physical address of their DTB, and then doing the ‘go 0x80080000’. With an available network connection, U-Boot can load images quickly and easily via TFTP. Without the DTB addr, U-Boot can’t parse the ‘memory’ node to determine the mem start/end boundaries, and will hang in dram_init()/query_sdram_size(). That’s most likely because U-Boot depends on some registers at entry to be set up similar to the kernel: If we intend to boot this kernel, we have to make sure that this area of RAM. U-Boot does have the capability to store a binary in RAM, and execute it via ‘go’ – we believe that you have done that in the comment posted #7 11/2/17 9:09am.
