    Sorry, I didn't see the second question in your post. The majority of the circuitry on our board matches the EVM board that we got over a year ago. I don't have the circuit diagram near me, but I'm guessing that the OMAP has a 300 MHz clock. Did you find the photos from the scope measurements...

    I'm using the OMAP-L137. I've been working on a project for it for about 1.5 years. The boot process has not caused any problems until I got the new boards. I am trying to boot from SPI flash, and the Winbond parts work, but the Numonyx parts flash, but won't boot. These are the same Numonyx...

    James McGloin
    Hi, I wish to flash a kernel and filesystem to SPI flash on a L138 custom board we have developed. We do not have any networking on the board so the uBoot flashing method will not work for us. Is the a method for combining uboot + kernel + CRAMFS so that I can use the sfh_OMAP-L138.exe -flash <UBL...

    Jason Ling
    I've spent some time trying to figure out the boot process of the OMAP L138 and would like some confirmation on my assumptions. 1.) The OMAP L138 has a "bootload" peripheral which comes up and executes a Rom Boot loader which is stored on a factory-programmed ROM located somewhere on...

    I agree with 1258021(aka GSR). The read command (0x03) is supported by the device as "Continuous Array Read (Low Frequency Mode)". The address is 22 bits in 512 byte mode (which you will have to use, as the addressing scheme in 528 byte mode is not compatible). Since this appears to be a...

    Hello - we are using a 32Mbit M25P32 SPI flash as the boot device on our OMAPL138 board. I am recompiling sfh_OMAPL138, but its not obvious what the parameters in DEVICE_SPI_MEM_params refer to in the SPI device itself. For example, on the EVM, which uses a P25M64 SPI flash, the blockSize and sectorSize...

    Hi Nikolay, thanks for your reply. Yes I think you are right, we will have to use SPI1 which has cs 2 and 3 reserved for "external devices". I read on here that there is some way to disable the flash after booting, but I am not sure how to do so. Also /dev and /tmp are mounted in flash memory...
