Hi,

following error in Serial Port (Attachment)

There is no attachment in your post. Could you provide the log?

Also can you share which SDK are you using?

Best Regards,

Mohammad,

Yes, this is a known issue with the K2H EVM and has been published in section 8.2 of the known issues archived by the board manufacturer on their website:

wfcache.advantech.com/.../EVMK2HX_Rev4_0_Known_Issues.pdf

This issue can be resolved by doing a UCD firmware update through the BMC using tools provided by the board manufacturer. Look under Software and Firmware section for the power management firmware binaries.

The python based update tool is also available from the Website under Support and Download Rev1.0/Rev1.1 Tab. documentation to update the firmware is described in the documentation included with the tool under :

BMC_EVMK2K_1_0_2_6-20160330\ks2evm-bmc-v1.0.2.6\docs

Let us know if you still observe the issue after the update or need help with updating the firmware.

Regards,

Rahul

even after running UCD updates and running BMC log files same error is coming it is working fine when we first power up the board but when i press RESET button i am getting as SoC POWER FAILURE please suggest how to solve it

It appears, that your UCD firmware has not yet been updated Here are the version numbers you need to see on the EVM.

Hello,

I have confirmed that the latest BMC tool and UCD configuration files has been released on advantech support download link below.

The "Board management controller binaries" has the latest "bmc_tool.py" and "Power management Configuration" has the latest "UCD configuration.txt" files.

i updated UCD with UPDATED firmware but still problem remains the EVM work fine when power is switched ON but when i RESET EVM it shows SoC_POWER _FAILURE please suggest me how to proceed forward

Mohammad,

SOC restarts from pressing the BMC reset button are not robust on all platforms. SOC starts from a power cycle are robust now that the UCD firmware has been updated. You indicate that you also have robust operation from a cold start. Please continue using the EVM from a complete power cycle.

i am having another similar EVM purchased along with this EVM but it is working fine with reset and complete Power recycle what may be issue in this EVM is their any hardware issue

Mohammad,

It is assumed to be a hardware issue in the implementation of the power sequencing and control between the BMC and the UCD9090. Several of these signals are floating or slowly decaying when the SOC power is turned off. This then causes the BMC to falsely report a failure during the subsequent start-up sequence. This has never been fully debugged on this EVM. The 66AK2E05 EVM that was designed after this one had this reworked extensively (BMC control code, UCD9090 programming and pull-down resistors on these control signals). The 66AK2E05 EVM robustly works through a BMC reset.
