RM44L520: ESM -> Stat3 error (When downloading basic Halcogen source to RM44L520)

Part Number: RM44L520
Other Parts Discussed in Thread: HALCOGEN, TMS570LS1224, SEGGER

hello. I was only using the TMS570LS1224 EVM, and after learning some basic usage, I chose a TI MCU (RM44L520) to apply to my first project and downloaded the source code generated by HALCoGen to the MCU for debugging.

I used the latest version of CCS and the latest compiler, and also used the generated sys_link.cmd without modification.

I put a simple code for confirmation only in the main function below.

As a result, in the _c_int00() function, the value of esmREG->SR1[2] becomes 0x80 as shown below.

After searching datasheet Tables 6-31 and 6-32, it was confirmed that FMC uncorrectable error - Bus1 and Bus2 accesses (does not include address parity error) occurred.

The debugger uses XDS200/Segger J-link and the editor uses CCS/IAR, but they are the same.

I referred to the answers on the forum, but it didn't solve the problem.
Since I am a beginner, I would appreciate it if you could easily tell me step by step which part needs to be modified/supplemented.

1. CCS linker menu options

2. sys_link.cmd settings

3. etc...

  • We found that there are differences between the TMS570LS1224 reference board and the sample board we prepared.

    We set the input frequency supplied to OSCIN to 25Mhz, which is listed in the RM44 datasheet as 5Mhz to 20Mhz.

    It appears that the ECC Error occurred due to the above problem.

    It can't be used at 25Mhz, right?

  • Hi Eun,

    Apologies for the delay in the response.

    It can't be used at 25Mhz, right?

    Yes, you are right. It can't be used for 25Mhz. The maximum main oscillator frequency should be 20Mhz.
