ROSCO Simulink-Invalid logical input for file

[moming64]

Hello,
I am running a single FAST simulation with the ROSCO Simulink,and trying to read the GBoxEff parameter from the ElastoDyn file and modify it in runFAST.m.However, the following error occurred:

Error reported by S-function 'FAST_SFunc' in 'ROSCO/FAST Nonlinear Wind Turbine/S-Function':
FAST_InitializeAll:ED_Init:ED_ReadInput:ReadPrimaryFile:Invalid logical input for file
"D:\openfast\test\ROSCO-main\Test_Cases\5MW_Land_Simulink../NREL-5MW/NRELOffshrBsline5MW_Onshore_ElastoDyn.dat"
occurred while trying to read Echo.

The value of "Echo" both in .fst file and ElastoDyn file has been set to "True",how should I fix this?
Thanks in advance!

Dear @moming64,

Which version of OpenFAST are you using? Is Echo on line 4 of the ElastoDyn input file?

Best regards,
