We are trying to bring-up the customized (OMAPL138) board in where the u-boot.bin(bootloader) was corrupted, we have configured board boot-mode to UART1.

Have connected the customised (OMAPL138) board to TERATERM COM1 with baud rate 115200, the expected BOOTME message pops-up upon POWER-ON the board.

Upon Flashing u-boot.bin using the sfh utility from TI OMAP-L138_FlashAndBootUtils_2_40 we are seeing errors attached . Please share your comments on this.

Hi,

[ This is an urgent request - unable to dig through all literature or videos to find answers in quick time and to avoid assumption based mistakes ]

The NIMU example (built successfully in CCS based on the script/batch file) guided we were guided in other post

e2e.ti.com/.../774782

But on execution, no IP address gets generated or no general application behaviour observed on connecting the Ethernet cable to the target side.

Please help us on these by direct pointers or quick inputs -

1) which are the configuration option involved (either in CCS gui or in direct files within the PDK ]

2) what CCS options to be set to run this demo in EVMDRA75X / TDA2xx / Jacinto processors - Cortex A15 ?

3) In the target side which Ethernet port should have Ethernet cable plugged ?

4) Will this demo example work for Static IP generation - cabled between PC and Target board ?

5) Will this target board / soc / pdk expect Cortex-M4 as the master target to enable and run the Ethernet driver and related demo app successfully ?

Thanks,

Sathiyan

Dear,

I did training PD with the Caltech Pedestrian data-set.

I converted *.descriptor to *.bin file using AdaboostTableGen.exe.

I'm reading the userguide of the "ObjectDetection".

After I replace the pd_adaboost_weight.bin to new one(then need not modification of the object_detection.cfg file), what I do?

I ran the analytics2 usecase with EVM board.

I'd like to apply the new weight training file to check the improvement of the PD.

Best regards,

Hi All

I have the same question regarding UART console in MLO .

How to change MLO UART console number? I have done all the changes and they are OK with uboot but MLO prints nothing.

The following lines are printed by MLO in GPEVM but I can not get them on my custom board:

no pinctrl state for default mode
no pinctrl state for default mode

The changes on /include/configs/am57xx_evm.h file do nothing about it.

Uboot console is OK.

We were working on DM8168 board. ARM processor is running on linux (baeed on EZSDSK), while we were running VoLIB components in DSP. We were able to establish the communication between both the cores using Syslink. But, I think syslink can't be accessed using CCS.

We have created shared memory using Syslink. We needs CCS to access that shared memory. We had some audio files in that shared memory which needs to be processed by DSP using VoLIB. I know that TI has limited support for DM816X boards. I just needs to know how does shared memory concept works in CCS and is it possible for CCS to communicate with Syslink shared memory. My CCS version is CCS 5.5.0.00077

We have a question about ”NIMU_BasicExample_idkAM574x_armExampleproject" of PROCESSOR-SDK-RTOS-AM57X.

We checked the sample code behavior under below both version pdk.

- pdk_am57xx_1_0_11

- pdk_am57xx_1_0_13

We success to run ping operation from PC when both TMDSIDK574(J10) and PC are connected to 100Mbps network by each ethernet cable.

But we failed to run ping operation from PC when both TMDSIDK574(J10) and PC are connected to 10Mbps network by each ethernet cable.

(We'd like also to attach teraterm console logs of pdk_am57xx_1_0_13 case as a reference.)

Question:

Do you have same experience?

We would appreciate if you tell us how to solve this problem.

(Why this example failed in 10Mbps network case?)

Hello, I have a problem with writing data to the SD card. When I using Hwi and Swi in my application, these threads interrupt my critical section when I writing data to my SD card and my data crashed.

When I don't use DSP (DSP evokes Swi) and Hwi_disable() and set task priority for other task with higher priority the problem does not occur.

How to put a critical section in the application where occur Hwi, Swi and higher priority tasks?

if(1)
{
	sprintf(fname, "Data_test%i.txt", licz);
	licz++;
	hwiKey = Hwi_disable(); //Disable all hardware interrupt
	
	int i;
	for(i = 0; i <200; i++)
	{
		taskPri3 = Task_setPri(taskMain_8, -1); //Disable taskMain
		//Critical section
		if ((fres = f_open(&fil, fname, FA_OPEN_APPEND | FA_READ | FA_WRITE)) == FR_OK)

			f_write(&fil, SD_BUFF_TEST, sizeof(SD_BUFF_TEST), &cnt);
			f_close(&fil);
			//The end of the critical section
			Task_setPri(taskMain_8, taskPri3); //Enable taskMain

The input is : "..\..\test\testvecs\input\trace_dump_0_768x320.y" and I get output "stats_tool_out.bin".

1. JdetNet is for object detecting, so how can I get the detecting results (bounding box, class, confs ) from "stats_tool_out.bin"?

2. If I want to test my own pictures, what should I do with my xxx.jpg ?

Hello,

I'm using CCS v.8.3.0 with TI RTOS 5.01.00.11 and I have a problem on AM335x ICEv2 board.

The SYS/BIOS is using for clock generating DMTIMER2 as default what I get after some debug time.

This timer should be disabled after reset as mentioned in Technical Reference Manual Rev. P (register CM_PER_TIMER2_CLKCTRL).

Also DMTIMER0 (register CM_WKUP_TIMER0_CLKCTRL) should be disabled, but directly after the start of debug (breakpoint on c_init), just after apply of gel script I see that both are enabled.

I was looking to delivered GEL file (TMDXICE3359.gel), but there is nothing about enabling of these timers.

Means first question is how these timers are enabled?

Another problem is that SYSBIOS was correctly working in debug, but not under Bootloader.

In Bootloader was crashing on check frequency part.

Now my understanding what is happening:

SYSBIOS default timer DMTIMER2 (for AM335x) is using as default 32kHz input frequency.

The CCS is changing register CLKSEL_TIMER2_CLK reset value CLK_M_OSC to CLK_32kHz clock. Here again I want to ask how, because I don't see it in GEL file.

The Bootloader is using default settings of CLKSEL_TIMER2_CLK means CLK_M_OSC and I can fix crash on frequency check with following configuration:

var DmTimer = xdc.useModule('ti.sysbios.timers.dmtimer.Timer');
DmTimer.intFreqs[0] = {hi: 0, lo: 24000000};

But after this, the debug code of course is not working.

Please can you suggest me some solution for this issue, how to fix that it works for both?

With best regards
