bootconsole [udbg0] disabled and fman_ucode versions for T1040D4RDB

Question asked by Wenjun Zhu on Apr 13, 2018

Hi! I have two questions.


Question 1: I am trying to boot fsl-image-core for T1040D4RDB and console hangs after bootconsole [udbg0] disabled.   Image packages are generated successfully and no error. Is there any solution for this? I am using Ubuntu 14.04.1 and minicom.


Question 2: There are only two fman_ucode files generated from SDK 2.0. They are both r1.1. But when I check my serial console the firmware is v1.0. Is there any way to generate version 1.0 using SDK 2.0?


Firmware 'Microcode version 0.0.1 for T1040 r1.0' for 1040 V1.0...Fman1: Uploading microcode version 106.4.14


These are the command I use to boot up the fsl-image-core:

//upload U-BOOT
=>tftp 0x1000000 u-boot-t1040d4rdb-64b.bin =>protect off 0xebf40000 +$filesize =>erase 0xebf40000 +$filesize =>cp.b 0x1000000 0xebf40000 $filesize =>protect on 0xebf40000 +$filesize
//upload RCW
=>tftp 0x1000000 rcw_1400MHz.bin =>protect off 0xec000000 +$filesize =>erase 0xec000000 +$filesize =>cp.b 0x1000000 0xec000000 $filesize =>protect on 0xec000000 +$filesize

//upload FMAN Ucode r1.1
=>tftp 0x1000000 fsl_fman_ucode_t1040_r1.1_106_4_18.bin =>protect off 0xebf00000 +$filesize =>erase 0xebf00000 +$filesize =>cp.b 0x1000000 0xebf00000 $filesize =>protect on 0xebf00000 +$filesize

//alternative bank
cpld reset altbank

//upload UImage and fsl-image-core
//Change ttyS0 to ttyUSB0
=>setenv bootargs ‘root=/dev/ram rw console=ttyUSB0,115200 ramdisk_size=10000000 log_buf_len=128K’ =>saveenv
=>tftp 0x1000000 uImage-t1040d4rdb-64b.bin =>tftp 0x5000000 fsl-image-core-t1040d4rdb-64b.ext2.gz.u-boot =>tftp 0x2000000 uImage-t1040d4rdb.dtb =>bootm 0x1000000 0x5000000 0x2000000

Thank you!
