似乎在连续写入两块不同的非零等等区域时会有问题？

[kaidegit]

目前版本有写入到非零等待区域第二块时错误的问题，log如下。

Error: Error while fastprogram: [41, 01, 01, 05]

根据我的串口log可以看到烧写0x0802e000部分时固件已经启动了，跑了一点条之后变为了Error: Error while fastprogram: [41, 01, 01, 05]

我猜测可能是启动打断了烧录的问题，所以我尝试翻转了写入顺序

                        Firmware::Sections(sections) => {
                            // Flash section by section
                            if address != None {
                                log::warn!("--address is ignored when flashing ELF or ihex");
                            }
                            // reverse sections
                            let r_sections = sections.iter().rev().collect::<Vec<_>>();
                            for section in r_sections {
                                let start_address =
                                    sess.chip_family.fix_code_flash_start(section.address);
                                log::info!(
                                    "Flashing {} bytes to 0x{:08x}",
                                    section.data.len(),
                                    start_address
                                );
                                sess.write_flash(&section.data, start_address)?;
                            }
                        }

然后确实能正常烧写了，但是只成功烧录了最后一块，并且烧的还是错的，感觉问题主要在这一块。

提供一个可以复现问题的hex

正常烧录的话log应该如下，串口PA9， 2M波特率

确认该问题.
需要确认下官方工具的协议时序.
