TMS570LS3137: ESM error at jump from bootloader

c sen

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

My bootloader does not perform any "Safety Init" tests, all are unchecked in halcogen. Bootloader is generated via halcogen 3.5.

There is a legacy app written via Halcogen 3.2. When execution jumps to this application from bootloader, first I see a Watchdog reset and then esmREG->ESTATUS1[2] is set indicating "RAM Odd Bank - ECC Uncorrectable Error".

I have another app written via halcogen 4.2. When execution jumps to this app from bootloader, I do not encounter any error.

on the app written with Halcogen 3.2, when I comment out pbist and ramECC related tests in cinit, I don;t experience the ESM error.

How could I fix this problem? any help/guidance would be great. thanks,

The app established via halcogen 3.2, this app runs fine if ran on CCS on its own, without bootloader. the same pbist related tests run on both cases , whether jump from bootloader or no bootloader. So, when jump from bootloader, what causes these pbist related tests trigger ESM group 3 error?

thanks,

Hello,

Did you compare the source code (sys_startup.c) generated by v3.2 and 3.5? Does the 3.5 version project have the abort.asm file?

Hello,

When doing RAM ECC check, the 2-bit ECC error will cause a data abort to be generated. The abort.asm is used to clear the ESM group3 errors (expected selftest error).
