Linux/DLPC3438: DLPC3438CZEZ / DLPA2000DYFFR and DLP3010FQK can't boot-up

Part Number: DLPC3438

Tool/software: Linux

in my systems, we use DLPC3438CZEZ / DLPA2000DYFFR and DLP3010FQK.

we use the same option between DLPC and dmd to DLPDLCR3010EVM.

as you know,DLPDLCR3010EVM is use the dlpa2005, but we use the dlpa2000.

and we use the firmware DLPC3438_6.0.0_Firmware.img is same the demo of DLPDLCR3010EVM.

but our hw-system can't boot up with the host_irq is always up not go to low.

so we think should use a new firmware or not ?

  • Hello User,

    The DLPDLCR3010EVM firmware will not work with your system. The firmware will change between using the DLPA2005 and DLPA2000, so you will need new firmware compatible with the DLPA2000 for your system to boot.

    Do you have alternative firmware to use? If not we can assist you further with this.

    hi, my name is jianyuan liu, from hangzhou guangli CHINA.
    my dlp system is support for our AR glasses.

    and i need the new firmware, thanks a lot.
    pls mail me the new firmware by my e-mail : jianyuan@lightin.com.

    but,
    i also have a try with the two FW "dpp343x_4.12.8_option1.img" and "dpp343x_4.12.8_option2.img" from shanghai support.
    the two FWs are all can't boot-up my hw-system with the dlpa2000 can't supply the correct voltage such as "Vrst" \"Vbias"\"Vofs".
    and i find out that the two option's bin(image or firmware) files are only different with "1" bit.
    so i think the two image(firmware) are all wrong.

    thanks a lot.

    hi, thanks a lot for your replay and support.
    but ,i'm sorry to say you, my e-mail box prevented the "bin" image files, as follow,
    " Symantec Mail Security replaced DLPC343x TI Design Firmware Installer.zip with this text message. The original text contained prohibited content and was deleted. "

    so,pls to sent me again by my another email: liujianyuan_cn@163.com .

    as you know, in my debug, we use the same design to DLPDLCR3010EVM.
    so pls tell me which "option" was used in your DLPDLCR3010EVM system.
    the option means DMD sub-lvds swap contol as descripted in datasheet page41(DLPC3433, DLPC3438).
