C5509A Sleep Mode - Author Unknown - Feb 20 21:27:00 2005
|
Anyone have any experience or comments on putting the C5509A into the lowest power sleep mode. The low power sleep mode stops the external crystal oscillator. You wake again with an external hardware interrupt (IRQ type thing) or RTC alarm. I've had a very difficult time getting it into this sleep mode and stopping the clock. Wake up is no problem. I've read all the app notes many, many times on setting everything correctly (USB to DPLL mode, stopping domains, etc.) before entering last idle state. Any hints? Thanks |

Re: C5509A Sleep Mode - kd7lmo - Mar 1 20:38:00 2005

This helped a lot. It is ALMOST working. If I call the TSK_sleep before I enter the power down mode, the clock does not stop. After I wake up from the RTC, I notice the IFR1 register is set to 0x0200. This bit corresponds to the DLOG interrupt. I've masked all interrupts before I went to low power mode. But it appears as though I'm still getting an interrupt that is preventing the clock from stopping. There is little information on the DLOG interrupt. It appears that many DSP/BIOS kernel events (such as though triggered by TSK_sleep) are logged to LOG_system. How can I disable this system event logging? I tried LOG_disable(&LOG_system), but that didn't work. If I have the DSP/BIOS | Message Log window open, the system sleeps correctly. I assume it is causing the JTAG emulator pod to correctly read and process the LOG_system messages. If I don't have an emulator, is there some set of pull up/downs on the JTAG pins to indicate a pod isn't present and to ignore all data log messages? Is there a document on the DLOG / BIOS interaction and operation?

DLOG is associated with RTDX, the JTAG transport mechanism for real time data exchange. You can disable RTDX in your BIOS config file and this should get the 5509A to deep sleep. Select the RTDX module in the config tool and disable RTDX, also under the HST module change Link Type to 'none'. Just so you know, disabling RTDX will make it so the BIOS Real Time Analysis (RTA) plugins don't update in real time - only when the target halts.

Thom, Thanks for the fast response and great help. That fixed it and the C5509A is now in low power, sleep mode. I wish TI had a good app note that shows all the steps required to get there. There are bits and pieces, but nothing that shows start to finish how to disable the USB clocks, idle all the domains, and other little tricks. Thanks again.
