  • Forum Post: Custom Board with LM3S59556 C1

    Andrea Sorio
    Hi My name is Andrea I designed a board with a LM3S5956 Cortex M3 micro, revision C1. The JTAG interface doesn't work. The LDO voltage regulator feeds 1.2V and not 2.5V! Any idea? Thank you in advance Best Regards Andrea Sorio

    elia49267
    Hi, The C1 revision of 9b92 need to start from 0x1000 because of the patch to the hardware bug. So i have a boot loader and i want to change it to start from 0x1000. In normal code that start from main i just change the linker flash origin start to 0x1000. But this change with boot loader...

    elia49267
    The boot_eth not only uses uip it is using UDP broadcast and two other things 1) BOOTP protocol 2) TFTP Protocol Both are not working fine on linux and unit and also on embedded linux like OMAP 138. The UIP i am suggesting is a TCP point to point , client server that is working everywhere...

  • Forum Post: Stellaris LM3S9B90 revision C and USB

    Einar
    I have been using the evaluation board EK-LM3S9B90 with a revision B chip for a product acting as a USB device. I have now received a prototype which is using a revision C chip, but I notice that neither the USB enabled boot loader nor my application handles USB. The device is not enumerated in any case...

  • Forum Post: Re: LM3S9B92 Flash programming problem

    Stellaris Paul
    I was confused and I thought you had unlocked and erased the patch, but apparently you did not. You cannot erase the entire flash on Rev C1 parts, which is what you have apparently, because the patch code is read only at address 0-0x00000fff. This is only for Rev C1 which requires this patch so yes this...

    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...

    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...
