TI中文支持网CC2640R2 启动初始分过程中icall_directAPI函数报ICALL_ERRNO_TIMEOUT错误,这个错误是INT问题，有时能正常启动后系统运行起来，但大部分时间是不行，
背景环境如下：
1，CCS7.3.,
2， cc2640r2_sdk_1_50_00_58,
3， cc2640r2_sdk_ble_example_pack_1_50_00_62中的hid_emu_kbd demo。
Viki Shi：
根据描述无法判断，是否对例程做了修改，具体是哪些？
PS:协议栈版本及CCS版本都太低，建议升级到最新版再测试

回复 Viki Shi:
1，修改硬件配置设置，把CC2640R2_LAUNCHXL修改为CC2640R2DK_5XD
2，修改进程ICALL_MAX_NUM_TASKS个数，由4修改为5
3，其他修改跟系统启动无关。仅仅是APP task 函数的简单修改.
另外 cc2640r2_sdk_ble_example_pack_1_50_00_62在TI官网是最新版本，这个版本对应的CCS是7.3， 是否还有更新的demo pack?uint32_t icall_directAPI( uint8_t service , icall_lite_id_t id, … )

很久没逛官网了吧，最新版SDK是3.40：

回复 Viki Shi:
因为我们需要基于HID keyboad的profile来开发应用，只有在扩展demo包cc2640r2_sdk_ble_example_pack_1_50_00_62里支持这个profile demo , 目前这个版本在官网显示是最新版本，但它对应的SDK包是1.50.00.58版本才能正常运行，看如下链接扩展包支持指导，
software-dl.ti.com/…/simplelink_example_pack_users_guide.html
另外，扩展demo包是否有比目前cc2640r2_sdk_ble_example_pack_1_50_00_62版本更新的，如果有，请提供下载链接。谢谢

sorry 我看错了，SimpleLink CC2640R2 SDK BLE Example Pack的话最新版确实是1.50.关于icall的问题，请参考以下的类似解答:
