data partition sizing

Using v14.4.1 of XMOS tools. I'm observing inconsistent results when sizing the data partition on an XCORE200 Explorer board. xflash --boot-partition-size 0x20000 --factory bin/app.xe gives ======flash info===== data partition size: 917504 page size: 256 num data pages: 3584 num data sectors: 224 da...

Re: AVB gptp blocking

This code in the Ethernet tile runs if (0 == i) debug_printf("rgmii ptp packet_ready()\n"); i_rx[i].packet_ready(); but, after a time, this code in media_clock_server.xc fails to run case i_eth_rx.packet_ready(): { debug_printf("mclk: ptp_recv_and_process_packet()\n"); ptp_recv_a...

AVB gptp blocking

I've run into a situation where gptp on an XMOS device is loosing pDelay request responses from the AVB switch it is connected to. This code is modified from the original gptp code XMOS provided. The code works fine on an XMOS multichannel audio board, but not the target hardware. My assumption is t...

xflash speed in production

Hi all, What is the theoretical fastest time to program a XLF208-256-TQ64 using xflash in a production environment? We are using xflash --quad-spi-clock 50MHz --factory xmos_factory.xe --loader xmos_loader.o --boot-partition-size 0x180000 --data info.dat and we observe programming times of 2 minutes...

Re: fl_startImageAddAt offset problems

We have given up using a length spec for the factory image. It won't work.

fl_getNextBootImage

I've read the docs for fl_getNextBootImage() fl_getNextBootImage provides information about the next upgrade image. Once located, an image can be upgraded. Functions are also provided for reading the contents of an upgrade image. Are there checks whether or not the next boot image is corrupt, or not...
