I'm working on an application using OMAPL138. In project my previous colleague using StarterWare.
I want to delete the STW and replace it with the PDK (currently used SYS/BIOS and mixed STW and PDK).
I encountered many problems (ex. function used by STW I have not found in a PDK).
Is removing STW from the project it's a good idea?

Hi,

We need POWERLINK solution on AM65xx. Do you know any third party can support it ? or have a plan ?
Do you know port GmbH or KUNBUS GmbH is preparing it ?
If they have, could you tell us schedule and contact person ?

bzero(&newtio, sizeof(struct termios));

Hi,

In technical reference manual 26.1.9.4.1, it says Ethernet MAC address comes from mac_id0_lo and mac_id0_hi.

I would like to know if the default value is all the same if the IC part number is the same?

E.g. all AM3357BZCZA30 use the same default MAC address for BOOTP?

Thanks.

Hi, I'm lookign for low power dsp options that have are byte-addressable.

I see in the C5500 compiler stddef.h and other files there are #define options (__TMS320C55X_PLUS_BYTE__).

I have also seen a readmeplus.txt in the compiler folder.

Is this C55x+ a commercially available option? - I can't see any reference to it on the TI site.

AM4372: USB Dual role and OTG

Part Number:AM4372

Hi Experts,

We would like to develop HOST and DEVICE roles products with AM4372.
It should operate as a DEVICE for normal and as a HOST if a wireless module is connected.
So, could you please let  me know what the Dual role function mean in the TRM.

According to e2e, AM437x does not support OTG.
However, OTG function is described in the source data ( device tree) or the block diagram for AM437x_GP_EVM.
So, is it possible to be the DEVICE or the HOST with AM4372?

Thank you very much for your kind check.

Best regards,
Hitoshi

Part Number:EVMK2H

Tool/software: Code Composer Studio

What boot-mode is used in EVMK2H? ARM-master or C66x-master?

If ARM-master mode is used and If I load the operating system Linux as is described in "Linux Getting Started Guide"

software-dl.ti.com/.../Overview_Getting_Started_Guide.html

 then will the kernels c66x be involved in work? 

Can I work with c66x under the control of the Linux system?

Second question.

In EVMK2H There is provided "0010:NOR SPI BOOT" mode (or No Boot/JTAG).

And if I load the operating system Linux as described in "Linux Getting Started Guide" is it loaded only in NOR whithout using NAND?

(NOR-flash is small !)

And one more.

Where BMC code of EVMK2H is located? In flash (NOR or NAND)?

If this code will be corrupted how can I restore it?

Regards, Alexander.

Dear Team,

My customer is designing HW using TDA3 and requesting maximum power consumption information on each power rails of TDA3 to design power rails.

I only find 'AutomatedPowerMeasurement' tool for TDA3, but I'm afraid it is hard for them to measure power using this tool.

Is there any other tool to check power consumption on each power rail of TDA3?

Thanks and Best Regards,

CCS/AM6548: AM654x R5F peripherals in CCS register's view not displayed correctly

Part Number:AM6548

Hi,

while trying to debug a problem with a TI-RTOS application running on a R5F core of a AM6548 on the AM654x_IDK board we came across a problem with the registers view in CCS. We wanted to examine the content of the MCU_TIMER<n> registers, but the CCS registers view apparently treats the MCU_TIMERs (and lots of other peripherals) as an internal bus firewall, i.e. it is displaying registers like CBA_CONTROL_i_j, CBA_PERMISSION_i_j_0 and so on. We had a look at C:\ti\ccsv8\ccs_base\common\targetdb\devices\AM6548.xml and it looks like many of the peripherals don't have the correct module definition. It also seems that the base addresses are often wrong:

<instance href = "../Modules/am65x/PSRAM0.xml" id = "MCU_TIMER0" xml = "PSRAM0.xml" xmlpath = "../Modules/am65x/" description = "" baseaddr = "0x45108000" size = "0x20" accessnumbytes = "1" permissions = "rw" />
                <instance href = "../Modules/am65x/PSRAM0.xml" id = "MCU_TIMER1" xml = "PSRAM0.xml" xmlpath = "../Modules/am65x/" description = "" baseaddr = "0x45108400" size = "0x20" accessnumbytes = "1" permissions = "rw" />
                <instance href = "../Modules/am65x/PSRAM0.xml" id = "MCU_TIMER2" xml = "PSRAM0.xml" xmlpath = "../Modules/am65x/" description = "" baseaddr = "0x45108800" size = "0x20" accessnumbytes = "1" permissions = "rw" />
                <instance href = "../Modules/am65x/PSRAM0.xml" id = "MCU_TIMER3" xml = "PSRAM0.xml" xmlpath = "../Modules/am65x/" description = "" baseaddr = "0x45108C00" size = "0x20" accessnumbytes = "1" permissions = "rw" />

We checked for updates within CCS, but there doesn't appear to be an update available.

Is this a known issue? Is there a fix planned?

RTOS/AM6548: TI-RTOS error message regarding dmtimer in TI-RTOS example applications

Part Number:AM6548

Tool/software: TI-RTOS

Hi,

we tried building a TI-RTOS example application following the instructions from the processor sdk documentation:

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_examples_demos.html#arm-cortex-r5

We had problems before with SDK version 05.01 where the SBL was unable to load the application from a SD card (see https://e2e.ti.com/support/processors/f/791/p/750685/2778897?tisearch=e2e-quicksearch&keymatch=am6546#2778897?).

The SBL problems are gone with version 05.02, but we get an error about dmtimer frequency mismatch:

[MCU_PULSAR_Cortex_R5_0] ti.sysbios.timers.dmtimer.Timer: line 1162: E_freqMismatch: Frequency mismatch: Expected 25000000 Hz, actual: 174906832 Hz.  You need to modify Timer.intFreq.lo to match the actual frequency.
xdc.runtime.Error.raise: terminating execution

There are older posts about a similar problem, but that issue appears to be fxied in the SYS/BIOS version that comes with SDK 05.02:

Defects Fixed in SYS/BIOS 6.73.00 (Fixes since SYS/BIOS 6.70.00):

SYSBIOS-689 dmtimer Timer_checkFreq() failure due to caching


We're not sure if the dmtimer would have worked with SDK 05.01, but at least we didn't get that error message back then when we loaded the application via the debugger. With 05.02 we get that error message both when using the debugger and when loading the application via SBL from a SD card.

Is there a known issue regarding the dmtimer stuff on AM654x R5F with SDK 05.02? Are there any instructions on how these things should be set up, in case we're missing some necessary manual setup steps?

Tool/software: TI C/C++ Compiler

We have bought a device AM437x Starter Kit. We are going to use the GUI matrix and make some new program. I have several questions for this device. Could somebody helps me?

1) Do we have a method to debug the board? there is a USB cable to connect the device with the host Computer, it seems there is no instructions about how to use it to debug

2) In the program we need to call some 3rd device drivers which are written under general Linux OS. When creating new project by CCS6, do we use CCS project or general C++ project?

      2.1) if using CCS project, should we choose Crosss GCC or Linux GCC?

      2.2) if using general C++ project, do we choose TI V15.12.1.LTS compiler or GNU V4.9.3 (Linaro) compiler? 

3) I noticed there is no g++ compiler in the list, I suppose those GCC or TI V15.12.1.LTS or GNU V4.9.3 compilers are all right to handle the C++ project and 3rd party c++ device driver?

Thank you very much for the help!
