Hi,
I am programming beaglebone black through the tftp. I am unsing the cutecom
for programming and following below steps,
1. Transfering u-boot-spl.bin through xmodem.
2. Transfering u-boot.bin through ymodem.
3. Setting up the static Ip on uboot.
4. Using the NFS and transfering kernel images through the TFTP.
5. The setting for bootargs are as follows
- * setenv NFS_BOOT "setenv fdtaddr 0x80F80000*
- * setenv loadaddr 0x80007fc0*
- * setenv serverip 192.168.10.11*
- * setenv rootpath /opt/BPL/nfs_rootfs*
- * setenv loadfdt 'tftpboot ${fdtaddr} am335x-boneblack.dtb'*
- * setenv loadimage 'tftpboot ${loadaddr}
vmlinuz-4.4.6-ti-rt-r14'*
- * setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs rw
nfsroot=${serverip}:${rootpath} ip=${ipaddr}:::::eth0 rootfstype=ext4
rootwait fixrtc'*
- * setenv bootcmd 'run bootargs; run loadimage; run loadfdt;
bootz ${loadaddr} - ${fdtaddr}'"*
- * saveenv*
- * run NFS_BOOT;*
During programming my observation is, whenever Ethernet status led's
doesn't blinks for the first POWER ON , the TFTP transfer fails. This
happens quite frequently, so my question to all BBB experts, Is there any
problem with my bootargs or it is problem of phy IC of BBB(lan8710)? I am
new to BBB and Linux programming so kindly help me to understand the
problem.
Thanks in advance,
Regards,
Nitin Chavan
