BluetoolDownloadMinidriver失败

你好，
我试图闪亮我们的BCM 20736S BLE模块。使用WICE Smart SDK 2.2.0，在WICE Smart IDE中，我有2个make目标（用于下载和恢复）：BLU-BCM920736TAGYQ32下载Bti DeVice地址=随机UART= COM91
BURE恢复BCM920736TAGQUQ32恢复UART= COM91
类似地，我们也希望使用CIPUADADEXE从命令行闪现：
CopulAD.EXE-ButoToLoope-端口%UARTHORT端口%BUDRATE 115200 -MIDIDRIVE .BCM920736TAGIQ32，UARTHI DISABLE，EEPROMEND WPIP1.HEX-BTP.BCM920736TAGYQ32，20736MEEPROF.BPT-COFFIG%文件FIENMEAM-HEX %-CHECKCRC-NoValue-DLMIDIDRiver SunCKSKEYSIZE 251
我们有一个自定义的PCB与2 FTI 232 USB到UART转换器，每个连接到一个UCM的BCM模块。它也有一个重置按钮的BCM，和一个按钮拉SDA到GND恢复。
我们使用这些序列来尝试闪存模块：
下载：按下和释放重置，启动IDE中的制作目标：按下复位和SDA，释放重置，等待一段时间，释放SDA，在IDE中启动目标（改变时间）
我在BCM重置时测量了RX PIN，假设它处于“HI”级别（3.3V）。在第三方论坛上，我看到SoeOne提到SDA也应该是高的，而不是低的，用于恢复，而不提供参考。我试过修改，没有效果。
其中任何一个在IDE中几乎都不起作用。1 50次没有错误，chipload，我在电脑上（通过32位），没有工作，我总是得到“bluetooldownloadminidriver失败”。在不同的PC（赢10）我曾经chipload到几次工作，但再也不是了。
你能提供任何暗示什么可能产生这种零星的闪光过程的功能？

  Hello,

I am trying to flash our BCM 20736S BLE module.
Using WICED-Smart-SDK 2.2.0, in WICED Smart IDE, I have 2 make targets (for download and recovery):
BLE-BCM920736TAG_Q32 download BT_DEVICE_ADDRESS=random UART=COM91
BLE-RECOVER-BCM920736TAG_Q32 recover UART=COM91

Similarly, we'd also like to use the ChipLoad exe to flash this from command line:
ChipLoad.exe -BLUETOOLMODE -PORT %UART_PORT% -BAUDRATE 115200 -MINIDRIVER .BCM920736TAG_Q32uart_DISABLE_EEPROM_WP_PIN1.hex -BTP .BCM920736TAG_Q3220736_EEPROM.btp -CONFIG %FILENAME_HEX% -CHECKCRC -NOVERIFY -DLMINIDRIVERCHUNKSIZE 251

We have a custom PCB with 2 FTDI 232 USB-to-UART converters which each connect to one the UARTs on the BCM module.
It also has a reset button for the BCM, and a button pulling SDA to GND for recovery.

We use those sequences to try to flash the module:
- Download: press & release reset, start the make target in IDE
- Recover: press reset & SDA, release reset, wait a while, release SDA, start make target in IDE (with varying timing)

I measured the RX pin at reset of the BCM, it is at "HI" level (3.3V) as supposed.
On a 3rd party forum I saw soneone mention that SDA is also supposed to be held high, not low, for recoevry, without giving a reference. I tried that modifcation, to no avail.

Any of this almost never works in the IDE. Like 1 of 50 times there is no error.
The ChipLoad, on my PC (wint 32bit), never works, I always get "BluetoolDownloadMinidriver failed".
On a different PC (win10) I once got ChipLoad to work for a couple times in a row, but not anymore.

Can you provide any hints as to what may produce this rather sporadic functioning of the flashing process?
