[参考译文] TDA4VM：问题：刷写 QNX 映像后、在 TDA4暂挂上、它无法启动。

工具与软件：

您好！  

我将使用以下软件包构建 QNX+RTOS SDK

RTOS：ti-processor-sdk-rtos-j721e-evm-09_00_01_01
QNX：ti-processor-sdk-qnx_j721e_09_00_00_03

QNX： qnx710

QNX BSP：/qnx710/bsp/ BSP_ti-j721e-tda4vm-sk_br-710_be-710_SVN981674_JBN18.zip

按照中提到的构建步骤进行操作：

在 QNX + RTOS 模式下编译成功。 但是、当我使用 SD 卡启动电路板时、我没有获得稳定的映像 u-boot 启动。
