Firmware upgrade UserGuide for MMDVM HAT(Simplex/Duplex/Repeater) made by BI7JTA

Important update ,from firmware v1.4.12

Frequency restrictions to avoid satellite interference. Please avoid the following ranges: 145.8-146.0 MHz and 435-438 MHz, otherwise firmware will not start.
tail -100f /var/log/pi-star/MMDVM-2018-11-21.log
Error message Received a NAK to the SET_FREQ command from the modem

NOTE: 
1)  WiFi SSID and PASSWORD BE REPLACE WHEN Restore Configuration!

2) If run firmware upgrade script error ,run Pi-Star OS first  **Important**

sudo pistar-update && sudo pistar-upgrade

1 ) Duplex HAT by BI7JTA VR2VYE

sudo pistar-vyehsflash hs_dual_hat
Radio/Modem Type "MMDVM_HS_Hat Dual Hat(VR2VYE) for Pi(GPIO)"

2)for Nano hotSPOT (BlueBOX)

sudo pistar-vyehsflash nano_hs

change Modem_Type to "MMDVM_HS_NPi Hat (VR2VYE) for Nano Pi(GPIO)"

*For old version HAT,

*If not successful,some old nano HAT need do more operation,connect the upgrade GPIO jumper, detail see here.

3)for RPi_Simplex hotspot

sudo pistar-mmdvmhshatflash hs_hat  

Change Modey-Type to "STM32-DVM / MMDVM_HS - Raspberry Pi Hat (GPIO)"

4)for MMDVM repeater board make by jTA

For V3_F446 

Upgrade logs:

20191002: add RSSi data display support

Change Modey-Type to "STM32-DVM / MMDVM_HS - Raspberry Pi Hat (GPIO)"

Open your ssh GUI http://pi-star/admin/expert/ssh_access.php  

User: pi-star  

Pass: raspberry  

Login and Ctrl + C then Ctrl +V ,run the follow scripts   

rpi-rw;  

curl -OL https://raw.githubusercontent.com/bi7jta/MMDVM_HS_firmware_VR2VYE/master/RepeaterV3F4/stm32flashV5;  

sudo chmod +x stm32flashV5;

curl -OL https://raw.githubusercontent.com/bi7jta/MMDVM_HS_firmware_VR2VYE/master/RepeaterV3F4/mmdvm_f4.hex;  

sudo killall MMDVMHost >/dev/null 2>&1 ;  

sudo ./stm32flashV5 -v -w mmdvm_f4.hex  -R  -i 20,-21,21:-20,21 /dev/ttyAMA0;  

#Please Power off then Power on(Not the reboot).  

For V1_F105

*Important* Just support use boot loader flash HAT firmware

The new firmware version is RPT_1.4.7 

New feature: Support POCSAG mode.

Download https://www.bi7jta.org/files/STM32DVM_F105/

Flash use USB 

Suggest this way,enter flash mode easy then GPIO

1）Use USB mode  

1.1 Disconnect STM32-DVM from the RPi host, GPIO and USB all disconnect,  

1.2 Insert JP jumper, short BOOT and VCC near P25 LED,  

1.3 Connect STM32-DVM to the RPi host use USB wire, then will endter flash mode automatic. PWR, ACT and DMR will bright, not flashing (Very important,if not as I description, disconnect USB and connect again) .  

1.4 Flash use USB (replace your .hex path, and download stm32flash,see Require libs )  

sudo stm32flash -w /usr/src/MMDVM/bin/mmdvm.hex -v /dev/ttyUSB0  

  

Require libs

Flash use ST-LINK (Not suggestion)

Buy a ST-Link ,then connect to the board ST-LINK interface, then open STM32 ST-LINK Utility, choose mmdvm.hex,then flash.
