Dear Expert,

Does our linux driver of ADS1015 on TI.com can support Kernel 4.14?

It's failed on my customer's side. failed information as below.

Hi, Jaden

Please look at my waveform and see if ZVS has been implemented. And I feel the rising edge of the main switch Vds is a little strange, do not know what is the reason, according to the principle should be vertical up.

I use my own customized am5718 board. I want to migrate the tda2xx vision SDK kernel to my board, but when I start it, I print an error: waiting for root device partition = 283ad381-02. I see some statements in the forum are due to DTS, but I use my own device tree. I can start normally by testing other kernels, and only the vision SDK can't start. Why?

Part Number: TPS65132

Hi, 

My customer is having problem reading the I2C register, may I ask that is there any extra setting need to be done from the external to enable I2C control or reading?

Since they are also using LP8556, I2C should worked fine. 

And they and also process write commend to TPS65132 by measuring the output of POS and NEG output. 

Can you help to let us know the reason?  

Please let us know if further information needed. I will help to confirm with customer. 

Thanks a lot for your help.

And the output of SN74LVC14APWR will be fixed to about 1V,could you help let your R&D  evaluate the risk of this application? And could you share the internal block circuit of SN74LVC14APWR for review?

Hi!

The problem occurred in my customer's set with BQ25890.
In case 1 below, it is normal, but in case 2, Vsys does not come on.

1. When charging, VSYS powers on.


2. If not charging, BAT power is present but VSYS power is not.

When connecting the charger and removing the charger while running Set, the VSYS power is turned off immediately.
If you check the symptoms, it works as if it is disabled even though the battery is connected.
The following is the BQ25890 register when the problem occurs with reference.

TPS65131-Q1: TPS65131 - Load Distance and Stabilization

October 27, 2019, 8:21 pm

Part Number: TPS65131-Q1

Hello:

I am planning on using the TPS65131TRGERQ1 device in a design, and will of course follow the evaluation module's recommended design and other recommendations. The output will be +12V / -12V, driven with a 3.6V / 17Ah Lithium cell.

The load the supply will be connected to is about 18 inches from the enclosure that houses the supply. With this in mind, is there anything I need to design in to help insure stability of the supply? I expect the current to be about 125mA maximum on either side. I would do the typical things like use twisted pair wiring. Would additional capacitance be of any benefit, provided the ESR is appropriate for the design?

Thanks for any feedback on this you can provide.

AM6548: How to simply use ICSSG0 ethernet in u-boot

October 27, 2019, 8:35 pm

Part Number: AM6548

Hello TI,

Let me describe my problem first. Under u-boot, I have successfully used ICSSG0 ehternet with the following script.

    setenv firmware_dir '/lib/firmware/ti-pruss'
    setenv ethact pruss0_eth
    setenv get_firmware_mmc 'load mmc 1:2 ${loadaddr} ${firmware_dir}/${firmware_file}'
    setenv start_icssg0 'rproc start 0; rproc start 1'
    setenv load_icssg0_pru0_fw 'setenv firmware_file am65x-pru0-prueth-fw.elf; setenv loadaddr 0x89000000; run get_firmware_mmc; rproc load 0 0x89000000 13040; rproc start 0'
    setenv load_icssg0_rtu0_fw 'setenv firmware_file am65x-rtu0-prueth-fw.elf; setenv loadaddr 0x8a000000; run get_firmware_mmc; rproc load 1 0x8a000000 5676; rproc start 1'
    setenv init_icssg0 'rproc init; run load_icssg0_pru0_fw; run load_icssg0_rtu0_fw'

First I executed 'run init_icssg0' to start icssg0. Then I found that I must execute this command 'run start_icssg0' before using icssg0 every time, for example using the command 'ping' or 'nfs' in the u-boot command shell! 

This is too much trouble. Is it possible to use icssg0 in a way that allows me to execute 'run start_icssg0' only once?

I tried to modify the driver source code so that the START command only runs once without running the STOP command. so I made the following changes in ‘u-boot/drivers/net/ti/icssg-prueth.c’

diff --git a/drivers/net/ti/icssg-prueth.c b/drivers/net/ti/icssg-prueth.c
index 67bbfb4ca6..c5c010dbdb 100644

+ return;
+
icssg_class_disable(priv->miig_rt[icssg], slice);

phy_shutdown(priv->phydev);

After making the above changes, under u-boot, before using ICSSG0, no longer need to run 'start_icssg0' , But icssg0 Ethernet does not work during booting the kernel.

Do you have a solution to save this problem?

LP5018: LED flashing scenario can be achieved?

Part Number: LP5018

Hi Team,

My customer is looking at LP5018, but there is one LED lighting scenario, in which we are unsure about LP5018. The scenario requires the LEDs to light up immediately when the system is plug in. LED driver is controlled by the SoC in the system. My customer is concerned that LED flashing will be delayed since SoC requires time to boot up and then give I2C command to LP5018. 

Can LP5018 do the above user scenario, i.e. LED flashing immediately when the system is power plug in? Or is there other LED driver suggestion or other way to implement such design? Thanks.

Best regards,

Hi Application team;

 

LM5025 has the hysteresis by turning internal current source on or off for UVLO function.

 

Can you tell us the delay time of turning off/on of the internal current source?

- From UVLO voltage increases >2.5V_threshold to changing 20uA current source to ON

- From UVLO voltage decreases <2.5V_threshold to changing 20uA current source to OFF
