RM46L852: RM46L852: Debugger consistently crashes at b _dabort right after start in adc

Bavi U M

Part Number: RM46L852

Hello Team,

i followed this youtube link https://youtu.be/YOBWhFE0LZg and generated the adc code and modified.

my problem is after flashing,The project is set to automatically run to main(). However, when I start the debugger, the green Resume button and the yellow Suspend buttons are greyed out. Only the red Halt button is shown and the debug window shows Texas Instruments XDS110 USB Debug Probe/CortexR4 (Running - A reset occurred on The Target). Clicking on Halt, the debugger exits and I'm returned to the Edit window.

If, instead of clicking the Halt button, I click on the Texas Instruments XDS110 USB Debug Probe/CortexR4 (Running - A reset occurred on The Target) line, the debugger halts, the yellow button is no longer grayed out but a green button is still greyed out. if i click yellow button all other button are highlighted and if i do step in the cursor keep on looping in this lines

i dont know what to do further.

b _dabort

_dabort
       stmfd   r13!, {r0 - r12, lr}; push registers and link register on to stack

        ldr       r12, esmsr3           ; ESM Group3 status register
        ldr       r0, [r12]

Hi Bavi,

Right now, i don't have RM46 board with me, i will get my board within a week.

If you are okay with it then fine, but if you have urgency then i will forward this thread to my colleague.

Thanks & regards,
Jagadish.

Hi Bavi,

Today i got chance to test your code and here are my observations:

1. The RM46L852 is a little endian device, but why you configured as big endian in project properties?

This blocks me while downloading.

2. The return value by the ltoa function is a character pointer and it won't return any length here, you are considering the return address as length right so it makes the code stuck in the below line

sciSend(scilinREG, NumberOfChars, command);

So, after correcting above modifications the code working fine at my end so please do the testing at your end also,

here is the corrected project:

2072.adc_test.zip

Hi Bavi,

To select the right COM port

1. First search the "Device manager" and open the device manager on your window search bar.

2. Now go to the Ports and verify the COM port number for User UART

3. Now select the same user UART COM port number into your Terminal options of CCS.

4. Once you did this and run the code then you should receive terminal data.

Thanks & regards,
Jagadish.

Hi Bavi,

I am receiving data as below for above code:

If still you are not getting any data on terminal, lets plan one live debugging session because the same code is working on my side and not working on your side right.

Thanks & regards,
Jagadish.
