Part Number: SM470R1B1M-HT
Hi,
I've made a simple board with the TMS470R1B1M, to evaluate the SM470R1B1M. I use IAR toggle flash demo (flash config), and the jLink jtag.
When I "download and debug" the demo code, everything works fine(port toggles). But after a powerdown, when I start the microcontroler (according PORST=0, 3.3V first, 1.8V second, and at last PORST=1) nothing append. From this point, I can only plug the jtag, and download again.
I'm probably wrong somewhere, or I missed something. I've read many things, but noway to my trouble.The demo is based on an eval board with a 7.35MHz oscillator, i've a 8MHz, should my problem is from that?
Another problem is that I can download and debug the demo project successfully in flash configuration. but in RAM configuration, I've got an error message "failed to measure CPU clock frequency, could not detect the CPU clock speed"
Thanks in advance.
