[quote user="Patrick_W"]Our board is currently in layout. I noticed that for our design VCCQ on the eMMC module was tied to 1.8v. Our TI Sitara's Vddshv11 pin is tied to 3.3v and the pull up's for the MMC DAT/CLK/CMD lines are tied to 3.3 volts as well. It's my understanding that these all must use either 1.8 volts or 3.3 volts. They cannot use different voltages. Is this true?[/quote] Yes, all these (VCCQ, VDDSHV11, MMC pins) must be used either 1.8V or 3.3V, cannot use different voltages. Also eMMC reset input signal should match this voltage level. [quote user="Patrick_W"]Is it also true that the only way to use the eMMC's HS200 mode VCCQ/VDDSHV11/pull ups for MMC_DAT0-8/pull ups for MMC_CLK/pull ups for MMC_CMD must all use 1.8 volts?[/quote] Yes, HS200 mode needs 1.8V. AM572x TI EVM eMMC do not support HS200 mode, as it is configured for 3.3V only. DRA75x TI EVM eMMC support HS200 mode as its voltage can switch between 1.8V and 3.3V, you can check DRA75xTI EVM schematics: Regards, Pavel

Forum Post: Linux/AM5728: About Processor SDK Supported Platforms
Part Number: AM5728 Tool/software: Linux Hi Champs, According to a AM57x Processor SDK page below, The supported EVM is only AM572x EVM. o PROCESSOR-SDK-LINUX-AM57X 04_01_00_06 ( software-dl.ti.com/.../index_FDS.html) On the other hand, in TI EP Wikipage below, the SDK supports AM572x EVM, AM572x IDK and AM571x IDK. o Processor SDK Supported Platforms and Versions ( processors.wiki.ti.com/.../Processor_SDK_Supported_Platforms_and_Versions) Could you please let me know which information is correct?

Can you also check if you can successfully enter into DeepSleep0 (mem) state, without using RTC as a wake-up source? Please have a try on your board: $ echo mem > /sys/power/state We need to check if the issue is related to RTC wakeup source or DeepSleep0 mode.

Forum Post: RE: Linux/AM5728: DSP Unload Failure on Processor SDK 04.00.00.04
[quote user="Rex Chang"] If I read it correctly, you use cmem block 0 for DSP1's FPGA buffer and block 1 for DSP2's FPGA buffer. Please refer to the post on July 6 in this thread, e2e.ti.com/.../604490 . The first 2 cmem blocks should be avoid. [/quote] We don't use OpenCL. We've been using the cmem configuration posted previously for all Processor SDK prior; is this some new requirement? Also, I see that there is now a 04.01 Processor SDK - would you expect better behavior for my issue with that version? Thanks

[quote user="Ravikumar G"]From the first link, the below node is mentioned to use timer7 as pwm. pwm7: dmtimer-pwm { compatible = "ti,omap-dmtimer-pwm"; ti,timers = ; #pwm-cells = ; }; From the above I did not understand where is "omap-dmtimer-pwm" driver in the SDK?. Blindly I have tried including the above node in my dts. But under /sys/class/pwm nothing got created.[/quote] This dmtimer pwm driver is available from PSDK v4.00 onwards (kernel 4.9.28). I would suggest you to switch to the latest PSDK v4.01 (kernel 4.9.41) or at least to PSDK v4.00 to be able to use that driver: {PSDK4.x}/board-support/linux-4.9.x/drivers/pwm/pwm-omap-dmtimer.c You should enable that driver through the menuconfig (CONFIG_PWM_OMAP_DMTIMER=y) as it is disabled by default in the am335x evm config file: {PSDK4.x}/board-support/linux-4.9.x/arch/arm/configs/tisdk_am335x-evm_defconfig Regards, Pavel
