We are using RM48L952 (144 pin package) and I find that when we program the attached Halcogen project into the chip, the chip fails to start. This change seems to be permanent i.e. the chip is lost forever. What happens is that when we debug with XDS100 and CCS, the cursto stops at c_init00. What could be the reason?
The main change I did was to reduce the VICLK1 by changing the divisor - we needed to run SPI at 100 Khz which was not possible with VCLK1 at 100 MHz. I set the divisor of VCLK1 such that VCLK1 is about 11.35 MHz, generated the code, compiled and tried debugging. It was taking a long time to show the cursor at the program line so I pressed pause. The code was cycling at the memory parity check while loop. I thought it was taking too much time because of low VCLK1, stopped the project, went to Halcogen and changed VCLK1 to 100 MHz again to check. Again I could not debug.
I programmed another working work - still the same issue.
Changed processor board, programmed the working project, it worked. Programmed the new Halcogen project again, debug stopped at c_init. Changed back to working project, debug worked.
I have attached Halcogen project which hangs up the processor. The difference between this and the project which stopped the processor completely is that the VCLK1 was set to 11.35 MHz.
What could be the issue?
