AEK-POW-BMS63EN showing incorrect cell voltages

Hey,

I am trying to build a battery pack with AEK-POW-BMS63EN BMS Slave Boards, AEK-MCU-C4MLIT1 as the Master Board, and an ISOSPI Translator. 

I have made a 4S Dummy Battery to check whether I could get the cell data on the serial bus from the Master Board. As suggested, I started working with the Example code titled 'SPC58EC-AEK_POW_BMS63EN_SOC_Est_SingleAccess_CHAIN application for discovery' but although the code got flashed onto the master board, I was still reading '0' values from the slave. 

Again, I tried the program titled 'SPC58EC - AEK_POW_BMS63EN_SOC_Estimation_Single application for discovery', since I realized that there was no ISOSPI Component added in the previous project. With this example project, I started getting some values but they seem incorrect. I am getting 5.8V on Cell 1 and 0V on the rest of the cells even when I checked the voltage on the test pins on the board between C0 and C1 is 3.8V. 

I am definitely doing something wrong here, I will take a look at the wiring again tomorrow. But, please help me out if anyone has faced this issue before. Thanks. 

PS: Should I try the example project titled 'SPC58EC - AEK_POW_BMSWTX_SOC_Est_SingleAccess_CHAIN application for discovery' as it supposedly has the latest driver code but it is for AEK_POW_BMSWTX Board right? Will it work for the AEK-POW-BMS63EN BMS Slave Boards?
