V0.9.5 brick

[nihaopaul]

tried the updated firmware, drivers and bootloader, after flashing the V0.9.5 but now have a dead product. broke out the jlink for following https://fineshang.gitbooks.io/wifimcu-based-on-emw3165-user-manual/content/chapter2_7.html but am unable to connect to the device .. or jlink complains that no device is found, any pointers? i wired up the clk and io line with gnd and vref going into 3.3.

Hi,nihaopaul The mcu is stm32f411ce. Have you tried another programming tool? The swd interface(D5/D6) is connected directely to mcu gpio(https://github.com/SmartArduino/WiFiMCU/blob/master/Document/WiFiMCU_SCH.pdf). it's not common that swd tools could not communicate with mcu.

We use SEGGER J-Flash 5.00i to flash the WiFiMCU as the following settings:(the mcu type stm32f411ve is choosed as there is no options for stm32f411ce)

Please feel free to email me(yangping@doit.am) if the problem is unsoled.

Best Regards, doit_yp

thanks! going to close this with a few notes as i run on OSX and how i solved it for me: first, this needs to update a little: https://fineshang.gitbooks.io/wifimcu-based-on-emw3165-user-manual/content/chapter2_7.html

a little schema could help for people and the j-link.

then, under the command line this worked for me: start the jlinkexe on osx with: JLinkExe -if SWD -device STM32f411VE then run the following commands (update to latest release, but keep the order)

r
erase
r
loadbin BCM43362-5.90.230.12.bin, 0x00002000
loadbin Bootloader_V1.0.bin, 0x8000000
loadbin WiFiMCU_Firmware_Integer_V0.9.5_20150905.bin, 0x800C000

the flash was successful and verified, but still is not accessible over usb, have i done something wrong?

[nihaopaul]

went back to 20150824 and it works again! only thing i done different was erase the device, will try the latest one after lunch again

[nihaopaul]

confirmed, V0.9.5 does not work, i had done a erase this time but still not working, will go back to 20150824

i lied! it does work! but the order needs to be: BCM43362-5.90.230.12.bin, bootloader, firmware
