  • Forum Post: LM3S3826 C1 Version Quality issue

    Caroline Wang
    Dear budy, One of my customer used Lm3S3826 C1 version and PP now but met some quality issue. As below, 2 Chips can not download firmware by JTAG 1) For those, 3.3V VDD is correct, but LDO is not 1.2V but 1.3V 2) Crystal can not work either. Another 2 Chips PINs is broken, One is SPICLK...

  • Forum Post: LM3S9B90 problem 1: JTAG often locked by unknown reason

    Steven54023
    We built many prototype boards with LM3S9b90, but JTAG just does not work. Some boards can be unlocked again by ICDI interface and TI flash programmer software, but some other boards just dead there, no way to program them. Even those “unlocked” board still have problem, some of them only...

  • Forum Post: LM3S9B90 Problem 2: EPI Host-Bus 16 mode does not work

    Steven54023
    When we use 16 bit mode to control 16-bit SRAM, we connect LM3S9B90's A1 to SRAM's A0. The processor has byte control signal to select lower and higher byte. The problem is the processor shift left all address pin by one bit, for example, their A1 is actually A0, but TI do not state this clearly...

  • Forum Post: LM3S9B90 Problem 3. USB does not work

    Steven54023
    Our USB just does not work at all, it is a simple circuit, all the pins and resistor is ok, but we could not find out where is the problem. In Errata RevB1, it has a USB bug, and we even changed the circuit according the Errata to make it as same as evaluation board (with RevB1 processor), but still...

  • Forum Post: LM3S5791 rev C1 work around

    Calum Mackinnon
    We are in the Beta program with our product. We use the TI LM3S5791 Rev C1 chip (we purchased 90 last year and are finally using them). Our chips have the silver dot on them (page 6 of the errata for the explaination). We program these units with a JTAG for our beta program. Address 0x0000.0000...
