Hi:
我想要測 Ble wificonfig 根據manual 設定
#define CONFIG_BT_EN 1
#define CONFIG_BT 1
#define CONFIG_BT_CONFIG 1
and
#define FTL_MEM_CUSTEM 1
接著 download image ,輸入 ATBB=1 出現以下log

#ATBB=1
[ATBB]:AT_BT_CONFIG[ON]

trace_uart_init: TRACE OPEN

有点像芯片内部设置出了问题。
用的是 8722DM 芯片吗？是开发板还是模组？从哪里买的？

HI:
從這裡買的
https://shopee.tw/iCshop－Ameba-RTL8722DM-mini-Board-(AMB-23)●368030501635●IOT-i.15050169.14578709472?sp_atk=9c3bb010-883c-4e56-ac56-1ec0289b70f9&xptdk=9c3bb010-883c-4e56-ac56-1ec0289b70f9

使用的是 latest github.
Compile tool :IAR
請問修改這個需要所有project 重 build 嗎?我只有重build km4 application 然後就download 到板子上,會有影響嗎?

4

应该不需要全部重新 build，km0_bootloader, km0_application, km4_bootloader 应该只需要上次 build 过就行

5

刚下载用 IAR compile 了没问题。或许你可以试试我compile 的 bin:
ATBB Binaries.7z.xml (431.7 KB)
下载文件后把 .xml extension 删掉再解压

6

Ok , I will try it later .thanks

still got same problem

我稍微trace 了一下似乎會在下列 function 中進入 ota_get_cur_index() == OTA_INDEX_1
這個case,然後check MERGE_PATCH_ADDRESS_OTA2(0x81f8000),是否有合法的 “patched” code,很顯然在我的platform是沒有的,這個行為看起來應該不正常.

uint8_t *hci_find_patch_address(void)
{
if(!CHECK_SW(EFUSE_SW_DRIVER_DEBUG_LOG))
{
hci_board_debug(“\nWe use DEBUG VAL:0x%x\n”, HAL_READ32(0x08000000, 0x3028));
}

if(CHECK_SW(EFUSE_SW_USE_FLASH_PATCH))
{
    //1
    return (uint8_t *)rltk_bt_get_patch_code();
}
else if (ota_get_cur_index() == OTA_INDEX_1)
{
    hci_board_debug("\nWe use BT ROM OTA2 PATCH ADDRESS:0x%x\n", MERGE_PATCH_ADDRESS_OTA2);
    HCI_PRINT_INFO1("\nWe use BT ROM OTA2 PATCH ADDRESS:0x%x\n", MERGE_PATCH_ADDRESS_OTA2);
    return (uint8_t *)MERGE_PATCH_ADDRESS_OTA2;
}
else
{
    hci_board_debug("\nWe use BT ROM OTA1 PATCH ADDRESS:0x%x\n", MERGE_PATCH_ADDRESS_OTA1);
    HCI_PRINT_INFO1("\nWe use BT ROM OTA1 PATCH ADDRESS:0x%x\n", MERGE_PATCH_ADDRESS_OTA1);
    return (uint8_t *)MERGE_PATCH_ADDRESS_OTA1;
}

}

这是全新的开发板吗？以前有没有上传过 OTA 的 code?
可以尝试一下把 flash 全部删空，然后再上传 image.

flash erase
flash erase585×798 95.2 KB

我找到問題了 system.bin 要打勾
CHECK_SW(EFUSE_SW_USE_FLASH_PATCH) 會去尋找system.bin (0x8003000) 的內容
如果true 就會從rltk_bt_get_patch_code() 拿到 patched code.目前你給的binary是可以work了.
if(CHECK_SW(EFUSE_SW_USE_FLASH_PATCH))
{
//1
return (uint8_t *)rltk_bt_get_patch_code();
}

我的build也ok了

我也遇到這個問題
解決方式
Flash Erase Addr : 0x08003000 size:4096
然後再重燒一次自己的firmware就可以了
