EVMK2H: SOC power failure error

ARMAN ALAEI

Part Number: EVMK2H

Hi,

i buy new EVMK2H. when i switch on the board, LCD show "soc power failure". when i looking for a solution i found out that i need to update bmc and ucd. so i program board to bmc version 1.0.2.6 using lm flash programmer. and then i update ucd using boot_tool.py. during update lcd show "main power stop complete" but after that again show "soc power failure". so what should i do?

best regards.

Hi,

Have you tried changing the value 70 in the below line to 256 in bmc_tool.py file, the line that needs to be corrected is bellow:
if 'I2CWrite' in line and len(line) < 70

Hi ,

I think I have same issue.
I have changed the value 70 but it doesn't work.
What value can I put ?
Also, I checked all methods to solve SOC POWER FAILURE.
My BMC and UCD files are the last updates and I check the elders.
TO load UCD I use NO-BOOT mode (0001).
I use 7.0 A and 12V power supply.

Best regards,

Florian
