How to to create a 1D Texture in Vulkan - vulkan

Question

I have a problem to create a 1D texture and I don't know how to solve it.
The texture is a float pData[256][4].
The code is like this:
VkDeviceSize imageSize = 256 * 4 * 4;
uint32_t texMemSize = ftsize;
VkBuffer stagingBuffer;
VkDeviceMemory stagingMemory;
VkBufferCreateInfo bufferCreateInfo = {};
bufferCreateInfo.sType = VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO;
bufferCreateInfo.size = imageSize;
bufferCreateInfo.usage = VK_BUFFER_USAGE_TRANSFER_SRC_BIT;
bufferCreateInfo.sharingMode = VK_SHARING_MODE_EXCLUSIVE;
if (vkCreateBuffer(device, &bufferCreateInfo, nullptr, &stagingBuffer) != VK_SUCCESS) {
throw std::runtime_error("failed to create buffer!");
}
VkMemoryAllocateInfo memAllocInfo2 = { };
memAllocInfo2.sType = VK_STRUCTURE_TYPE_MEMORY_ALLOCATE_INFO;
VkMemoryRequirements memReqs2 = {};
vkGetBufferMemoryRequirements(device, stagingBuffer, &memReqs2);
memAllocInfo2.allocationSize = memReqs2.size;
memAllocInfo2.memoryTypeIndex = findMemoryType(memReqs2.memoryTypeBits, VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_COHERENT_BIT);
if (vkAllocateMemory(device, &memAllocInfo2, nullptr, &stagingMemory) != VK_SUCCESS) {
throw std::runtime_error("failed to allocate memory 2!");
}
vkBindBufferMemory(device, stagingBuffer, stagingMemory, 0);
void* data;
vkMapMemory(device, stagingMemory, 0, imageSize, 0, &data);
memcpy(data, pData, static_cast<size_t>(imageSize));
vkUnmapMemory(device, stagingMemory);
delete pData;
//
VkImageCreateInfo imageInfo = {};
imageInfo.sType = VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO;
imageInfo.imageType = VK_IMAGE_TYPE_1D;
imageInfo.extent.width = static_cast<uint32_t>(256);
imageInfo.extent.depth = 1;
imageInfo.extent.height = 1;
imageInfo.mipLevels = 1;
imageInfo.arrayLayers = 1;
imageInfo.format = VK_FORMAT_R32G32B32A32_UINT;
imageInfo.initialLayout = VK_IMAGE_LAYOUT_UNDEFINED;
imageInfo.usage = VK_IMAGE_USAGE_TRANSFER_DST_BIT | VK_IMAGE_USAGE_SAMPLED_BIT;
imageInfo.sharingMode = VK_SHARING_MODE_EXCLUSIVE;
imageInfo.samples = VK_SAMPLE_COUNT_1_BIT;
imageInfo.flags = 0; // Optional
imageInfo.tiling = VK_IMAGE_TILING_OPTIMAL;
if (vkCreateImage(device, &imageInfo, nullptr, &tftextureImage) != VK_SUCCESS) {
throw std::runtime_error("failed to create image!");
}
The code give me always the runtime error "failed to create image", I tried to change some things like the format, the extent, etc but I can't solve it.
I believe that the mistake is only in the imageInfo part because the first one run ok.
