解決 wordpress 自動 Update 的問題

發佈日期: 作者:
回覆

Step.1 先到 FileServe.com 申請帳號，他會寄給你一個 FTP Account.
Step.2 到 Wrodpress 下設定 Auto Update 的 FTP 相關設定。

若看到：

Unable to locate WordPress Root directory.
Installation Failed

的錯誤訊息，則在 wp-config.php 檔案中加上以下幾行：

/* Fix WordPress autoupgrades on Byethost.com */

putenv('TMPDIR=' . ini_get('upload_tmp_dir'));
if(is_admin()) {
add_filter('filesystem_method', create_function('$a', 'return "direct";' ));
define( 'FS_CHMOD_DIR', 0751 );
}

以上參考: Unable to locate WordPress Root directory. Installation Failed

另外，也要注意，wordpress 檔案目錄的權限設定是否正確。

Step.1 啟動 TFTP service

# sudo /sbin/service tftp start

Step.2 變更 TFTP root directory （如果有必要的話）

TFTP root directory 的預設路徑是在 /private/tftpboot
如果想要變更的話，請修改 tftp.plist 的 tag，如：

/usr/libexec/tftpd
-i
/Users/fly/tftp

修改完畢之後，tftpd 需要重新啟動

# sudo /sbin/service tftp stop
# sudo /sbin/service tftp start

Step.1 新增 /etc/udev/rules.d/51-usbblaster.rules 內容如下

# USB-Blaster
BUS=="usb", SYSFS{idVendor}=="09fb", SYSFS{idProduct}=="6001", MODE="0666",
PROGRAM="/bin/sh -c 'K=%k; K=$${K#usbdev};
printf /proc/bus/usb/%%03i/%%03i$${K%%%%.*} $${K#*.}'",
RUN+="/bin/chmod 0666 %c"

特別注意： 上面敘述”BUS==…”要在同一行

Step.2 新增 /etc/fstab 內容如下

usbfs /proc/bus/usb usbfs devmode=0666 0 0

Step.3 執行下面指令 或 直接重新開機也可

sudo mount /proc/bus/usb

SystemVerilog Interface 的 inout port

發佈日期: 作者:

發現一個現象，
當使用 SystemVerilog Interface 時，
若 Interface 內有用到 inout，
則該訊號不能宣告成 logic，
必須要宣告成 wire，
不然如果與非 interface 寫法的 inout port 相連時，
NC 會回報錯誤：

ncelab: *E,CUVMIO (../tb/tb.sv,58|48): port connections to inout ports must be collapsible, that is, they must be nets of the same size.
