可以了...謝謝

原來可以降級
降級完成 還是不能用 XDD

Hi yiming

您可以打開MPLAB X IDE > Tools > Embedded > MPLAB Harmony 3 Content Manager

在MPLAB Harmony 3 Content Manager > Local Packages

找到dev_packs、csp，可以選擇相對應版本做降級(如附圖)

謝謝

如下面的圖所示 hamony 3 文件版本不符合，是電腦的版本比專案版本新太多
請問該如何處理?

設定如下圖 是不是有什麼設定錯誤的呢??

我試著建立一個新的專案(空的) 設定保護Bit
燒錄後程式還是可以讀回來

將未保護的CheckSum燒錄到ID的功能在ATSAMHA1E16AB無效?

ID menory 都是0xFFFF 完全沒看到CheckSum
將HEX載入IPE後 ，ID menory 一樣是0xFFFF 完全沒看到CheckSum

這功能在PIC是可以使用的，在ATSAM是無法使用嗎?

哇~~我看到了
CheckSum:NA
那ATSAM有類似的功能嗎? 還是要手動將CRC32填入ID ??

我找到一段說明 他的設定方式又不太一樣 他的說明我看了不是很理解

Question
How to set and check the security bit in software (without power on reset) ?



or



The SSB command is used to set the Security bit. However, the Security Bit does not seem to be set until a power cycle is done. Is there a way to get the Security bit to be effective immediately without power on reset?

Answer
The security bit is read by the hardware only after a reset. For setting the security bit through software, first set the fuse bit using SSB command, then do a software reset using NVIC_SystemReset() API, which resets the MCU.



The below code will set security bit and give software reset. After the device resets, it turns on the PB30 pin.

因為我目前的專案無法開啟Harmony ,所以我新開了一個專案進入Harmony 把那段程式碼放到了我的專案下再進行編輯...但程式還是可以讀回來...是那裡少做了嗎???

#ifndef __DEBUG
const unsigned int __attribute__((space(prog), keep, address(0x41004000))) SET_SECURITY_BIT = 1;
#endif

我有將那段程碼放到initialization.c 中,再重新編凙後用IPE燒錄以PICKIT4，發現燒錄玩後程式還是能夠讀取回來....

是不是還有其它地方也需要修改???
