Unable to write to registers of timer0 for OMAP-L138
Hi,
I am testing baremetal driver for TIMER0 module on DSP side of OMAPL138. I am able to create executable image and able to program image with help of IPC. The problem that I am facing is, the register writes that I am performing are not successful. For example if I write value of 0 to TGCR register and read back, the value is not reflecting properly. I have verified that the base addresses and offset I am using are proper as, I am able to read proper REV ID for TIMER 0 module.
From one of the link I came to know such issues will happen when the clock to the module is not provided properly. I checked if I can to any thing w.r.t PSC setting for TIMER0, but there are no register relevant to TIMERS
I have attached product.bld and product.bld.xml that I used for creating BIOS image.
please note that timer64bit_noos is executable file name and omap_l138_64_bit_timer_plus_drv.c","halconfig.c" and "timertest.c are source files.
Please let me know where I am going wrong or give some pointers
Following are package details,(Please visit the site to view this file)

Debugging slavecore (DSP) using syslink and gdb
Hello,
I'm using OMAP-L138 LCDK heterogeneous target board, XDS200 debugger, CCSv6.1.2, bios_6_35_04_50, ipc_1_25_03_15, syslink_2_21_01_05 and xdctools_3_25_03_72.
I'd like to debug DSP core application running on linux (ARM-core) with gdb and syslink.
I almost found the solution about development environment except slavecore debug using gdb or any solution.
TI's wiki explained "Debugging slave cores running SysBios" but it is insufficient to solve the problem. http://processors.wiki.ti.com/index.php/CCS_Debugging_of_Linux_Applications_with_GDB
Anyone help me?

Reading binary file via fread() in OMAP-L138 / C674x simulator
Here's my setup:
Host PC: Windows 10 64-bit
CCS: Version: 5.5.0.00077
Simulator: C674x cycle accurate simulator, little endian
I am trying to read a binary file using fread(), see source code below. However, the data appearing in the memory browser is incorrect.
Each element in the binary file is a uint8, and the values of these elements are as follows:
[1 2 3 .. 10 5 5 5 ....]
(i.e. count from 1 to 10 followed by lots of 5).
However, what I actually get is this:

Changing SYSBIOS Default Timer
Hi,
I have an application where I need to use timer 0 to generate a very fast pulse. This is on the ompal137 on the dsp and arm side. I can accomplish this by telling the clock module to use timer 1 leaving timer 0 for the pulse generation. If I disable the clock module it defaults to timer 0 and I have not figured out how to tell sysbios which timer to use without using the clock module. The documentation is really scarce on this topic. Sadly the only timer exposed to the outside world is TM64P0_OUT12 so that side of the timer is exclusive for the ADC convert clock.
What I'm trying to do, since the OMAPL137 has two 64 bit timers from which SYSBIOS grabs one 32 bit unchain mode, is to control which timer SYSBIOS uses. I need to allocate halves of the 64 bit to different things. For example DSP uses timer 1 lower half and ARM timer 1 upper half.
On the ARM side I'm also running SYSBIOS and I'm not sure if both OS can use the same timerid for example timer 1. If not, is it possible to assign in sysbios one half of timer 1 to the DSP and the other half to the ARM?

OMAP-L138 LCDK Code Composer JTAG error
Hi,
I just bought a OMAP L138 and a XDS100v3 JTAG emulator for a school project, but when I set up the target in code composer I always get the following error when testing the connection. My LCDK is plugged in to the 5V cable and the XDS100 to the miniusb port.
An error occurred while hard opening the controller.
-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver or utilities.
The value is '-180' (0xffffff4c).
The title is 'SC_ERR_CTL_NO_TRG_POWER'.
The explanation is:
The controller has detected a target power loss.
The user must turn-on or connect the power supply for the target.
[End: Texas Instruments XDS100v3 USB Debug Probe_0]
Any help will be appreciated.
Thanks

How can I use Ethernet to send something value??
In the enet_lwip.c example, I check the IP address of the LCDK in the TeraTerm.
And I check the mac address and IP address of the LCDK in the Wireshark.
But, I don't know why IP address and Mac address appear in the wireshark. Why??
I would like to proceed with the use of other Ethernet, let me know if you have any other examples or manuals. Please....
I want to send another value using Ethernet. What should I do??
I use the C6748 Development Kit(LCDK), TMS320C6748. And Compiler is CCS V5_5.

Regarding OMAP-L138 and C6748 overshoot and undershoot values
Hi,
Under absolute maximum ratings, AC transient overshoot/undershoot values is mentioned as 'DVDD + 20% up to 20% of signal period'.
For example, if DVDD = 3.3V and signal period = 0.1us (10MHz), then transient overshoot specification would be 3.3V + 20% (=3.96V) for 0.02us.
How should I calculate undershoot transient specification? Is it that -0.2V swing is allowed below 0V for 0.02us?
Please correct me if I am wrong.
Awaiting for your reply . . .

Archana Rao

C6748 RBL behavior: ECC uncorrectable error
Hello,
What does RBL behave if it reads NAND block 1 which is not a bad block and uncorrectable read ECC error is happen? It assumes it could read AIS magic word (0x41504954) correctly. It gives up booting or ignores and tries to boot up?

Hi Champ,
Could you please let me know if there is any negative impact on DDR2 throughput when I set IOPWRDN bit in VTPIO_CTL and PWRDNEN bit in DRPYC1R on C6748 to allow the input receivers to save power?

RE: L138: end-of life
[quote user="Shankari G"]
I came across that the hardware board, "Zoom OMAP-L138 EVM" from the "Logic-PD" has released the EOL. This EOL is for the "Evaluation module" and not for the processor, "OMAPL138". May be you are asking about that??
[/quote]
Hello,
I was going to start a new thread, but this one seems relevant. We wanted to purchase more of the Zoom OMAP-L138 EVMs, but those appear to be EOL. Can you tell me of any way to get more of those, or the next suitable EVM/Development kit for the C674X processor?

AM1705 problems when trying to use AIC3106 in Linux
Hello guys,
First of all, my board has the following hardware:
CPU: AM1705
SPI Flash : K0XMFI011 (Spansion) - 4MBytes - Connected to SPI0
Nand Flash: S34ML01G200TFI000 (Spansion) - 128MBytes - Connected to EMIFA
SDR SDRAM : AS4C16M16SA (Alliance Memory) - 32MBytes - Connected to EMIFB - Only one RAM chip
Ethernet : LAN8720a
Audio : TLV320AIC3106 controlled via I2C1
Power : TPS65023
Now my question:
So far I managed to have my board almost ready with the exception of the AIC3106.
Every time I want to output sound (by playing a file or by using the command speaker-test) the system resets and starts with the U-boot prompt.
I have tried several commands and checked the board-da830-evm.c file but I don't know what to modify.
Attached you can find my (Please visit the site to view this file) and my (Please visit the site to view this file).
Also when I try the following commands I get the following response, so I think that the chip is being detected.
aplay -l

root@da850-omapl138-evm:~
Even I can read the registers via I2C by using the following command line:
root@da850-omapl138-evm:~# i2cget -f -y 1 0x18 0x40
0x00
root@da850-omapl138-evm:~# i2cget -f -y 1 0x18 0x33
0x04
root@da850-omapl138-evm:~# i2cget -f -y 1 0x18 0x11
0xff
root@da850-omapl138-evm:~# i2cget -f -y 1 0x18 0x10
0x80
root@da850-omapl138-evm:~#
So it seems that it can access the chip via I2C.
root@da850-omapl138-evm:~# i2cdetect -F 1
Functionalities implemented by /dev/i2c-1:
I2C yes

However I realized that the MCASP signals show no activity in these signals:
DA830_ACLKX1 = aic_bclk
DA830_AFSX1 = aic_wclk
DA830_AXR1_0 = aic_dout
DA830_AXR1_5 = aic_din
I rechecked the pinmux settings and they are OK. Attached you can find my (Please visit the site to view this file).
The only exception is the DA830_AHCLKX1 that is being driven by an external 24.576MHz oscillator which also drives the AIC3106.
What can be wrong?
I will really appreciate your help.

Hi, I have a question regarding EMA_BA[1:0], both programming and logical addressing?
I am actually interfacing an external asynchronous UART using EMIF. I want to ask what actually happens on EMA_BA[1:0] pins, if I try to access it using EMIF. Or what is the actual program and logical address scheme? How will those EMA_BA[1:0] and EMA_A[13:0] will behave?
