I try that unsuccessfully again. It surprised me that bootargs haven't got updated from uEnv.txt file. uEnv.txt uname_r=4.7.8-armv7-x3 bootargs=earlyprintk console=ttyS2,115200
However, I did change tty from the u-boot command line directly, resuming boot process with "=> boot" and "=> run bootcmd"(I tried with both because I didn't know which is correct) , and got the same freeze after Starting linux kernel ... output. Here is my output: => editenv console edit: ttyS2,115200n8 => boot switch to partitions #0, OK mmc0 is current device SD/MMC found on device 0 Checking for: /uEnv.txt ...
