IPNC DM385 stage2启动停止在 start application 0x81000000

Other Parts Discussed in Thread: DM385, DMVA3, DM388

编译时指定参数为:

#####################################################################################
#CONFIGURATION
#####################################################################################

SYSTEM_PLATFORM := IPNC
#SYSTEM_PLATFORM := EVM

# Build configuration
#APP_BUILD_CFG := debug
APP_BUILD_CFG := release

# Binary to boot from NAND or SDCARD
BINARY_MODE := nand
#BINARY_MODE := sd

# Values are "DM385" and "DM812x"
IPNC_DEVICE := DM385
#IPNC_DEVICE := DM812x

# Values are "LOW_POWER" and "FULL_FEATURE"
IPNC_CONFIG := FULL_FEATURE
#IPNC_CONFIG := LOW_POWER

# Memory foot print
#MEMORY_CONFIG := 256MB
MEMORY_CONFIG := 512MB

# UBIFS mtd-utils mode
MTD_UTILS_MODE := 64bit
#MTD_UTILS_MODE := 32bit

使用的DDR3为BOM表的中的  K4B2G1646C-HCH  *2 = 512MB

编译通过后,通过串口烧至Nand中,stage1一切正常,信息如下:

U-Boot 2010.06 (Apr 09 2014 - 15:36:29) DM385_IPNC_3.50.00

DM385-GP rev 1.1

ARM clk: 600MHz
DDR clk: 533MHz
L3 clk: 200MHz
IVA clk: 450MHz
ISS clk: 400MHz
DSP Default OFF
DSS Default OFF

DRAM: 1 GiB
NAND: HW ECC BCH8 Selected

Using default environment

The 2nd stage U-Boot will now be auto-loaded
Please do not interrupt the countdown till DM385_IPNC prompt if 2nd stage is already flashed

## Starting application 0x81000000

红色字段处停止,请问可能是什么原因?

有什么办法排查问题,我只有串口线可连接。


  • 你好,

    请问你使用的软件版本是?你使用的IPNC参考设计是最近拿到的么?新拿到很有可能的是REV2的板子。

    注意IPNC RDK 3.8里面有硬件REV1/REV2的区别。

    # Hardware Revision: REV1 or REV2 that the Software to be built for
    # REV1 is the older design which has higher power design (initial design)
    # REV2 is the new low power design which has low power numbers compared to older design
    # Please note: DM8127 runs with REV1 design with 3.3V I/O
    # And DM385, DMVA3 has support for both REV1 and REV2 and has 1.8V I/O
    # And DM388 supports REV2 only and runs with 1.8V I/O
    #HARDWARE_REVISION := REV1
    HARDWARE_REVISION := REV2

  • 你好!谢谢你的回复!

    我的软件版本是IPNC RDK 3.5,使用的参考设计是最近拿到的。

    我们的参考设计是DM385-IMX136,但实际量产的板子DSP是DM388,我没有对应的RDK。

    悲催。。。

  • 你好,

    如果你购买的是Appro DM385-IMX136, 你应该可以从Appor的FTP下载到最新的IPNC RDK。请和Appro联系。

  • 我也遇到一样的问题了,楼主怎么解决的。我也是3.5的rdk
