Part Number: TMS570LS1114

Hi,

My board nERROR is pull down.

To better understand what cause the problem I went into the the ESM register with CCS:


To understand the meaning of 0x80, I went to the reference manual to find:


After searching in the docs and online, I can't find any additional information about how to interpret the 0x80.

Where in the documentation can I find more information about the ESM register and how to read it?



Thanks,
Gabriel

    Hello Gabriel，

    The ESM integrates all the device error conditions and groups them in the order of severity. Group1 is used for errors of the lowest severity while Group3 is used for errors of the highest severity. The ESM channels assignments are in Table 6-35 of Datasheet.

    ESM status1: Group1[31"0]

    ESM status4: Group1[63:32]

    ESM status2: Group2[31"0]

    ESM status3: Group3[31"0]

    ESM status1=0x40 --> FMC correctable ECC error

    ESM status3=0x80 --> FMC uncorrectable ECC error
