Hi TI,
i use 6AO1.1 code source, and i want to optimize boot time, but i cant find Android o related documents. i find android m related documents.http://www.ti.com.cn/cn/lit/an/sprac30a/sprac30a.pdf.
Do you have any android o optimize boot time documentation?Whether the optimization process of android M/O is the same?

On my AM335x Evaluation Module (GP EVM) rev 2.1, with SDK (ti-processor-sdk-linux-am335x-evm-04.02.00.09) , I am able to boot Linux and run applications. But with default prebuilt images, Kernel boot messages are coming on LCD instead of serial console. How to route those messages to serial console. Please note my SPL and Uboot messages are coming on serial console but not kernel boot messages. Please guide me.

i would like to know about the functioning of ROM boot and how it does. Also, i am willing to know what are components that are initialized during u boot is used along with the start and end address of components in U-boot. My main purpose is to make custom U-boot for my new hardware board. i am looking for a way to reduce the size of u-boot, is there any procedure to built and compile to reduce the size of u boot.
thanking you,

Hi,
We are able to boot Linux from NAND flash ( using ti-processor-sdk-linux-am335x-evm-04.02.00.09 SDK) on AM335x Evaluation Module (GP EVM) rev 2.1. Now I want to communicate to SPI flash present on GP EVM from my C application in user space. Please guide me for the same. Where to find SPI flash drivers? What header files to include?
Thanks in advance.

Hello, TI Experts,
Our customer sent us a question about ARM SMP debug with PROCESSOR-SDK-RTOS-AM57X 05_00_00_15 on TMDSIDK574.
(We use CCS Version: 8.1.0.00011 )
We success to SMP debug with the "POSIX-SMP Demo" on TMDXIDK5728 based on the below wiki.
We also found the proper cross-trigger halt behavior on A15_1 based on the below wiki.
http://processors.wiki.ti.com/index.php/SMP_Debug
But we cannot found the cross-trigger halt behavior on TMDSIDK574.
(Please see attached pdf)
Question:
Do you have same experience on TMDSIDK574 with the "POSIX-SMP Demo"?
Our customer start to evaluation with TMDSIDK574 for their next product.

Hi,
I have Vision SDK version 03_03 (Linux on A15) running on TDA2x EVM (Rev H).
Vision SDK Image was built keeping MAKECONFIG as 'tda2xx_evm_linux_all' in Linux+BIOS mode
My usecase has a requirement to give audio alerts(.wav files of duration < 2s) , hence I have enabled audio on TDA2x EVM.
Please refer https://e2e.ti.com/support/processors/f/791/t/688263 for details
I hear glitches before and after the audio alerts are being played out(very frequently).
I have verified that the wav files don't contain any glitch.
To debug the issue I tried playing out a silent wav file, and still the glitch was heard.
(Silent wav generated by 'sox -n -r 44100 -c 2 silence.wav trim 0.0 3.0')
Is this a driver related issue ? Any fix is available for this ?

I want to access the first address 0x1000000(physical address) on a SRAM chip(8bits/512KByte), CPU is the AM4376, and no OS(pdk_am437x_1_0_10).
If I disable all the MMU and cache, It can work(I can get the active chip select signal from the oscilloscope). but because of other requirements, I have to enable the MMU and cache, the code is:
MMUConfigAndEnable();
CACHEEnable(CACHE_IDCACHE, CACHE_INNER_OUTER);
this functions is in the file:C:\ti\pdk_am437x_1_0_10\packages\ti\starterware\examples\example_utils\example_utils_mmu.c
but the program was throwed into AbortHandler interrupt.
How to change code to access to the first address 0x1000000(physical address)?
also, I notice that in function MMUConfigAndEnable(), there are this structure:
mmuMemRegionConfig_t regionOcmc =

Hi,
I have a question about AM572x GPMC_CLK.
Our customer are replacing from AM437x to AM572x.
They are going to use GPMC as NOR Flash Interface Synchronous mode.
From AM572x datasheet(sprs953d) page.246 Table 7-26, it seems that gpmc_clk maximum frequency is 88.6[MHz].
The maximum frequency of AM437x is 100[MHz], but AM572x GPMC_CLK is 88.6[MHz].
They want to know the reason why the GPMC_CLK maximum frequency of AM572x have decreased from AM437x GPMC_CLK.
And also have following question:
Have functions and mechanisms added such that performance is not a problem even if the frequency is decreased?
best regards,

Hi,
I train a new model, and runs well in in tidl_model_import.out.exe, and the result is shown in attachment.
Then I run the model in EVM TIDL_OD usecase, it comes out the unexpected result.(show in attachment).
At last, I run the model in CCS, and also got unexpected result. I check the trace_dump files between CCS and tidl_model_import.out.exe, and all layers are unmatched except input data layer.
So could you please help to check my issue. and if prototxt and caffemodel is needed, please provide email.

Hello
I’m looking for the ability to make GPMC-read commands using EDMA or similar to not load the ARM/DSP.
At the moment my device is set to “External 16-bit pseudo-SRAM (pSRAM) device” multiplexed address/data for an FPGA.
Can I control EDMA externally by an FPGA?
I have read about GPMC_DMA_REQ and other GPMC and DMA related in TRM but not sure.
Do I need to use this register: GPMC_PREFETCH_CONFIG1 and how?
Kind regards

Hi team,
My customer reports a random issue to causing no output in I2S during using our AM3352 with voice record and SD R/W.
please see below schematic, they have a series 100ohm and 100pf cap in the MCASP0_AHCLK line, and we check this clock signal integrity is good. Now we suggest to remove these components, this random issue seems no happen again yet. we still cannot understand, this RC should only related to signal integrity, do you think there is any potential link to this?

Hello,
In all Sitara Linux SDKs so far there is opkg package manager in linux-devkit/sysroots/x86_64-arago-linux/usr/bin.
We use it to edit the filesystem image before deploying to target, mainly to remove unneeded packages.
However, in SDK 5.00 (latest at this time) this opkg executable does not work.
Steps to reproduce on Ubuntu host with installed SDK 5.00.
1. create directory rootfs in home, and cd rootfs
2. sudo tar xvf ~/SDK/filesystem/tisdk-rootfs-image-am335x-evm.tar.xz from SDK/filesystems, and cd ..
3. sudo ~/SDK/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/opkg -o rootfs list
There will be no output.
strace-ing opkg execution shows this (after initial libraries loading etc).
open("/home/USER/rootfs//tmp/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy/sysroots/x86_64-arago-linux/etc/opkg", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

exit_group(0) = ?
+++ exited with 0 +++
opkg commands to remove some package will fail similarly, with a message "No packages installed or removed.".
This procedure has always worked till and including SDK 4.03. strace-ing older opkg does not show these strange
long names xxxxx/yyyyy that are indeed found in the SDK 5.00 libopkg.so.1.
So the question is: is the host opkg in SDK 5.00 usable to edit the targetg filesystem image,
and if so, what are the options, environment variables, etc. to achieve this.
Thanks

Hi Bill
After discussion, we give up eMMC booting on AM437x GP EVM. Your sugestion is good but I think it's too complicated to me at now, and the deadline will coming soon. I will make a research in future.
Now I am trying to build a smaller image using the snapshot of the source packages in Processor SDK release (ti-processor-sdk-linux-am437x-evm-05.00.00.15 ) but I can not download git2_git.linaro.org.toolchain.gcc.git.tar.gz by “am437x-evm-linux-sdk-arago-src-05.00.00.15/get_build_sources.sh am437x-evm-linux-sdk-arago-src-05.00.00.15/source_pkg_list.txt” command or web browser from software-dl.ti.com/.../
However, I have tried to build arago-base-tisdk-image without git2_git.linaro.org.toolchain.gcc.git.tar.gz to see what happens. I also attack a build log file until 37% for you to consider.(Please visit the site to view this file)
Hope receiving feedback from you.
Thank you.
