Update History

When you are using F/W after Boot 1.3 Version, you should check the memory area in the project setting(Both Boot and App).

Memory area of Boot Project(Boot after v1.3)	Memory area of App Project(Boot after v1.3)

Boot V1.3 history

v1.3.2 Stable

• Bug fixes:
  • Fixed pin mapping : DSR pin of WizZ750SR-100/105/110

v1.3.1 Stable

• Bug fixes:
  • When exception situation of TCP Connection - Class C private IP When the module IP and Remote IP is 192.168.xx.xx and third ip is different for each, ARP request operation is not transmitted.(This part had deleted)

v1.3.0 Stable

• Bug fixes:
  • When APP firmware is uploading using the configuration Tool and Board is power off, the product not operate.
  • DHCP Lease Time : when DHCP_DEBUG enable, DHCP Lease Time is fixed as 10 second.
    • DHCP lease time is modified to use it that information of received packet from DHCP Server.
  • The Status LED(PA_07) of WIZ750SR_1xx doesn't operate.
    • The Status LED(PA_07) of WIZ750SR_1xx is modified. Turning on an LED and making it blink once per second.
  • Compare DHCP Server IP : When DHCP OFFER Packet receive from DHCP Server,the DHCP server ip in packet compare with previous DHCP Server IP.
• Improvements:
  • The ISR address have changed to fixed address. The ISR address of APP did no more have to need copy and use in Boot.

Caution

• V1.2 Boot + V1.2.x App : Working
• V1.2 Boot + V1.3.x App : Working
• V1.3 Boot + V1.3.x App : Working
• V1.3 Boot + V1.2.x App : Not Working

latest F/W version(Boot V1.2)

v1.2.9 Stable

• Improvements:
  • Added in order to remove some unused functions
  • Modified flag of socket when socket function use(Non Block)

**

Boot V1.2 history

**

v1.2.8 Stable

• Bug fixes:
  • Fixed pin mapping : DSR pin of WizZ750SR-100/105/110

v1.2.7 Stable

• Bug fixes: All bug fixed described at upper v1.3.0 and v1.3.1 except Impovements.

v1.2.6 Stable

• Bug fixes:

  • If serial data packing 'time' option is less than 500ms, the first serial data(+++) ignored in GW mode.

• Improvements:

  • While IP address allocate using DHCP, the device can be made searchable using the Configuration tool and it can change the mode(AT mode <-> GW mode).
    • While IP address is allocating using DHCP , it can change the AT mode. It can show that the status of channel change from ATmode to OPEN in Configuration tool. So AT command didn't operate.

v1.2.5 Stable

• Bug fixes:

  • Modyfied the setSn_DHAR() Address offset.
  • Modyfied the WIZ750SR-110 HW_Trigger pin.

• Improvements:

  • If remote ip address is multicast address, enable multicating and set Sn_DHAR, Sn_DIPR, Sn_DPORTR before open socket

v1.2.4 Stable

• Bug fixes:

  • Serial data packing 'time' option does not work if serial command mode switching code is disabled.
  • Fixed typo of debug message

• Improvements

  • Added the PHY init stabilization code
  • Restore TCP connection status function to Status Pin (WIZ750SR-100/105/110 only)
    • The Status pin now acts as an 'HW_Trigger' pin(Input at booting) and a TCP connection status pin(output).

v1.2.3 Stable

• Bug Fixes:

  • Fixed an issue where the pin states could not be saved correctly if the user's GPIO is set to 'Digital Output'

• Improvements:

  • From this version, AppBoot mode supports TCP unicast search function
    • Until the previous version, AppBoot mode only supported the UDP search function
    • This is an enhancement to enable firmware update even in device control using TCP unicast search function in new configuration tool

• Changes:

  • The function of the STATUS pin that was responsible for the TCP connection status indicator function has been changed to Command mode switch trigger pin (HW_Trigger).
    • This changes only apply to the WIZ750SR-1xx product family (WIZ750SR-100/105/110, change to maintain compatibility with WIZ100SR)
    • The HW_Trigger pin up to v1.2.2 will no longer work with v1.2.3. The STATUS pin acts as the HW_Trigger.

v1.2.2 Stable

• Bug Fixes:
  • Stabilize the network operation of the W7500P devices
  • Error in setting function in App_Boot mode due to 'TR', 'SC' command processing failure
  • Applied the missing TCP retransmission timeout-value change

v1.2.2 Pre-release

• Bug Fixes:

  • Internal bug fixing (PHY init)
  • Char serial packing option(delimiter) setting does not correctly apply some hex codes

• Improvements:

  • Changed the location of the flash erase operation function during network firmware update
    • Now the application area flash memory is erased after socket establishment of TCP connection for the firmware update
  • Extended serial debug message added:
    • If this option is selected, users can check the sent and received data via the serial debug port. (WIZnet S2E tool GUI version 0.4.0 or later)

• Changes:

  • Changed the TCP retransmission timeout-value from 250ms to 200ms(return to default value)
    • The TCP timeout can be adjusted by the TCP retransmission retry count added in firmware version 1.2.0.

v1.2.1

• Improvements:
  • Enhanced operational stability when performing configuration data save and factory reset functions

v1.2.1 Pre-release

• Bug Fixes:
  • 'Character' of serial data packing option is not set correctly

v1.2.0

• Bug Fixes:
  • Data loss problem due to unintended delay in RS-485 mode (WIZ750SR-RS485 only)
  • Incorrect command processing problem: If the processing of a command set containing unsupported commands via Ethernet is sent to WIZ750SR, the device only responds a result until the error occurs
• Improvements:
  • Command added:
    • TR: TCP retransmission retry count adjustment function(WR, param range: 1 ~ 255)
    • BU: AppBoot update function (WO)
  • Changed the firmware update mechanism:
    • The app-backup area is no longer used and flash update operation is only performed in AppBoot mode
  • Now an error message about command processing will be output only during serial command mode operation
• Known Issues:
  • 'Character' of serial data packing option is not set correctly
    • This issue will be fixed in firmware version 1.2.1

v1.1.2

• Bug Fixes:
  • MAC address changed problem when device settings are saved (very occasionally)
  • Delayed response to search in config-tool when connecting to server in TCP client mode
  • Force socket close when fw update fails occurred
• Improvements:
  • Supports serial baudrate up to 460.8kbps
  • Added device profiles of WIZ750SR-1xx series to project source code

v1.1.1

• Bug Fixes:
  • Firmware update timeout function error in AppBoot mode
  • 10M Ethernet fixed error (W7500P only)
  • Invalid parameter of FW command (firmware update)
• Improvements:
  • Command added: AppBoot mode switching function(AB)
  • Initial boot latency(1500ms) has been removed

v1.1.0

• First release : 2016
