    Dear Sir, I already implemented the Ethernet function on 6437 EVM board with NDK, and would like to port it to 6431. But the setting in ".gel" file and "DSP/BIOS Config" file really differ a lot. (Cache, RAM, SRAM, DDR2 ...) In NDK's example, there is even SRAM in the memory...

  • Forum Post: Why the ethernet throughput drop to 15M bit/s on 6431? What's the resonable ethernet speed for 6431?

    Eric Fang
    Dear Sir, When I use 6437 EVM, my ethernet thorughput is about 80M bit/s, which is acceptable. But when I port my project to 6431, the ethernet throughput drop to 15M bit/s, aound 1/5 of 6437's speed, is that normal? I know the DSP clock of 6431 is 297MHz, 6437 is 594MHz, and the DDR2 bus width...

    Hi, Tim, Although it's a bad news for me, I still wants to thank you for your reply. Please let me know if you have any idea to speed up the Ethernet throughput. Thank you! Best Regards, Eric Fang

    Eric Fang
    Dear Matt, I am sure that there is SPI activity. I do set the bootmode. In order to debug, I boot with 24-bit SPI boot, then connect 6431 DSP with emulator. The code in my SPI flash will dump some logs in DDR2 memory. I am still studying these logs. Current status is that when I burn a smaller...

    Dear Tim, I can boot from SPI now. The problem is that I didn't set the PSC well. Gel file turn on all the power, but I didn't do that in my project. Really appreciate your help!! But I have another problem now, the UART interface is dead with SPI boot. UART can work when I load symbol...

    Dear Sir, I have problem with SPI flash booting on 6431. Please refer to the attached .cfg file. I convert a .out file to .bin. with the .cfg file. Is there anything wrong with my config file? I am very sure that the flash writing process is correct. Therefore, I think there is something...

    Eric, Since you seem to be having lots of problems related to Gel file functions that are missing when you burn a flash image, you might want to take a look at the board support library that was installed with your dev kit. Mine was in the CCS directory/boards/evmdm6437_v2\lib\evmdm6437bsl. If you...

    Eric Fang
    Dear Sir, When I use 6437EVM board, I can get a 30 frames per second frame rate. But when I port my project to DM6431, the frame rate becomes 15 f/s. I know the DSP clock change from 594MHz to 297MHz. Therefore, I change the "vpss_div" vaviable from 11 to 5 in the gel file. But I...

    Eric Fang
    Dear Sir, I already studied the spec spru 342, 871, 978 about power saving on 643x. I write some API to disable peripheral and set PLL in bypass mode(27MHz). But when I enable the peripheral and set the PLL back to 297MHz, my system can not work anymore, all the functions are dead. Is there any...

    Dear Sir, I have Ethernet function in my application, and it works well before.

    Hi, Juan, I think the data in DRAM is not modified by other tasks. I did some experiment to observe the Ethernet error. When I clear all the data in DRAM to 0 before I run the Ethernet application, the ethernet function can work well. If I don't do that, sometime it works, sometime it doesn't...
