RM48L952: RM48L952

Hi Suresh,

Are you getting this issue for the first time for this particular board? or you ran the code for few times then you are seeing this issue?

Error-1170: This is usually caused by either a hardware failure on the board or invalid code on the MCU flash that causes it to reset itself continuously. Have you programmed any code to the flash before? If it is caused by the invalid code, please try this procedure to let CPU enter a debug state:

1. Open the target configuration window, and launch the selected the configuration
2. Switch to debug window.
3. Press the reset (nRST) button and hold it.
4. Click “Connect Target” immediately after you release the nRST button.
5. The board should be connected after couple tries.

Hi jagadish,

No this is not first time we are getting this issue. Board was working fine initially.

We have tried more than 300 times by pressing nRST button still getting same error popup message.

We have tried with with different codes also still same issue persists.

Hi Suresh,

My sincere apologies for the delayed response, i was off for some days, so didn't get any time to look into this issue again.

Are you still stuck with this issue?
