Question 1:In the process of using jlink, sometimes "firmware-firmware" can be inexplicably lost, causing Jlink to become a brick.
Question 2:At the end of 2013/4/17, the latest version of MDK is 4.70a, with two important updates being
Code HintsAnd
error prompt,So there is a need to upgrade, but after the upgrade, your debugging tool Jlink in the firmware also to upgrade, but after the upgrade ~~~o (∩_∩) o~ So, so ~ ~ ~
Required raw materials: "Brick" jlink One (Own), Universal Jlink firmware one, Sam-ba software. http://pan.baidu.com/share/link?shareid=475095&uk=2668446171http://download.csdn.net/detail/fovwin/5269945
Step 1 Erase FLASH
Power-on-
Jlink and Pc,jlink and development boards need to be connected, if the latter is not connected, the "voltage is not enough" similar to the hint. Pull High ERASE (short jumper), wait 20 seconds (actually measured 30 seconds higher success rate) power off, restore ERASE (remove jumper).
The ERASE location of type a jlink:
ERASE location of type B Jlink:
Location of the C-type Jlink ERASE:
Step 2 Restore BootPower up again (because the firmware has been erased and the USB device is not recognized at this time)
Pull the high TST (short jumper) wait 10 seconds (the actual measurement is better than 25 seconds or more). Power off. Restore TST.
Step 3 Burn the new firmwareInstalling SAM-BA Software
Run Sam-ba software, select port and target board model
Load firmware and download
Will prompt if you need to unlock FLASH (unlocked cannot be downloaded)
Wait for the burn write to complete, and then select Do not select write protection
after the end of step 4, power back up, and the full state is resurrected. At this point, you can use the old version of the MDK to debug and download, of course, I am here to use the mdk4.70a version, so continue. Debug with mdk4.70a, Prompt for upgrade, select "Yes (Y)"
the side effect after the update is that you cannot use the old version of MDK to debug and download, note. Lucking....ps: Resources are from the network, only for learning, the consequences, do not chase across the province.
Jlink V8 firmware fix (support mdk4.70a)
