Hello, i am having trouble trying to update the firmware and I don´t know where is the error.
I tried updating with bossa, i follow the steps in the wiki:
https://wiki.newae.com/Manual_SAM3U_Firmware_Update.
path of the bin: hardware\capture\chipwhisperer-lite\sam3u_fw\SAM3U_VendorExample\Debug
But when i exit the program, I still have the message saying my firmware is outdated.
I tried to update firmware with the steps on the api, but I have an error entering the bootloader mode.
Code:
import chipwhisperer as cw
scope = cw.scope()
target = cw.target(None, cw.targets.CW305)
programmer = cw.SAMFWLoader(scope=target)
programmer.enter_bootloader(really_enter=True)
Warning: Could not connect to “NewAE USB (CWLite/CW1200)”. It may have been disconnected, is in an error state, or is being used by another tool.
After that I checked if the ChipWhisperer is disconnected but it is not.
I have a ChipWhisperer-Lite (Capture + UFO), the UFO is CW308 and I am using VMWare.
Update:
I have manually enter in the bootloader mode, and I use the method of the firmware path but there is an error.
Code:
import chipwhisperer as cw
programmer = cw.SAMFWLoader(scope=None)
programmer.program(’/dev/ttyACM5’,‘chipwhisperer/hardware/capture/chipwhisperer-lite/sam3u_fw/SAM3U_VendorExample/Debug/SAM3U_CW1173.bin’
Error:
Hardware method:
Code:
import chipwhisperer as cw
programmer = cw.SAMFWLoader(scope=None)
programmer.program(’/dev/ttyACM5’, hardware_type=‘cwlite’)
Error:
COM5 is connected to VMWare.
