Sleep low power mode wakeup example problem

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

I am using concerto board (TMDXDOCKH52C1). I am currently trying to learn how to make my board in sleep mode.There is an example code in C:\ti\controlSUITE\device_support\f28m35x\v201\F28M35x_examples_Dual. I tried that code and followed the instruction. But all the four pins (GPIO0, GPIO1, GPIO2, GPIO3) are 3.3 volts which is obviously not correct. Can anyone help what can I do to let the code work.

Thanks in advance.

Hi Bin!

Do you run your project at standalone mode? The fact that the Dual examples are not intended for runing at debug mode.

Igor

Hi Igor

Yes, I did. I made it standalone and reset the power. I checked the four pins voltages which are always 3.3 volts. Any ideas?

Thanks,

Bin

Hi Igor,

I found out that each time when I halt the program in debug mode, the program stopped at two places which are

"while (FlashCtrlRegs.FBPRDY.all != 0) {}" in c28 core and while (HWREG(FLASH_CONFIG_BASE + FLASHCTRL_O_FBPRDY) != 0) {} in m3 core.

So I am thinking the program is trying to make these two parts to sleep but it could not, so just checking these two lines forevery. When I commented these two lines the program seems working but maybe this is not correct. Any suggestions?

Regards,

Bin

Hi Bin!

Perhaps this will be useful 0647.F28M35x_Workshop_2-0.pdf.
