linux板子vscode gdb 远程调试

板子：hi3556v200

交叉编译工具：arm-himix200-linux

主机：win10+虚拟机的ubuntu16.4

gdb:gdb-8.2.tar.gz

1.在ubuntu交叉编译gdb（Remote 'g' packet reply is too long解决）

建议修改gdb8.2/gdb目录下面的remote.c解决Remote 'g' packet reply is too long

修改：

  /* Further sanity checks, with knowledge of the architecture.  */
  if (buf_len > 2 * rsa->sizeof_g_packet)
    error (_("Remote 'g' packet reply is too long (expected %ld bytes, got %d "
         "bytes): %s"), rsa->sizeof_g_packet, buf_len / 2, rs->buf);

修改为：

  /* Further sanity checks, with knowledge of the architecture.  */
  if (buf_len > 2 * rsa->sizeof_g_packet) {
   rsa->sizeof_g_packet = buf_len ;
   for (i = 0; i < gdbarch_num_regs (gdbarch); i++) {
       if (rsa->regs[i].pnum == -1)
