HM901 1.085Beta7/HM802 1.003Beta7 firmware released [2014-03-27]

By HiFiMAN at hifman.com

Firmware Update Instruction:

1. Please download the new firmware zip file first and then copy it to your SD card (Do not change the name of the firmware file or decompress it). Only the FAT32 SD card can be used.

2. While pressing the HOME button, hold the Power key up until the HM-901 is power on. After the screen is on, release the power key. Then release the HOME button until the hifiman logo disappears. Now the player will be in recovery mode.

3. Wait until the first picture shows on the screen. The system will be updated automatically.

4. After the update is done, power off the player and then reboot it to finish the whole process.

Bug issued:
1. Optimize the response speed of audio process and shorten the time.

2. Improve the SD card responding mechanism and significantly decrease the possibility of player crash caused by SD card hot-swamp.

3. Adjust the update logic and prohibit the user to operate during upgrade to avoid player crash. Add the function to judge the capacity of SD CARD--skip updating if its capacity is not changed, and power on the player faster.

4. Recover the player from being crash as the long playlist (especially All Songs) can take up much storage.

5. Recover the player from being crash when the last song ends under the mode of Repeat All.

6. Recover the player from being crash if the player is switched from the mode of shuffle to repeat under gapless play mode.

7. Issue the bug of channel reverse on special occasions.

8. Adjust the display content and order of some lists.

9. Support wv(WavPack) files.

10. Support Korea in language setting and complete the localization of added strings.

11. Support dock.

HM-802 v1.003 beta版固件下载链接:
http://down.hifiman.cn/HM802/beta/1003b7/update.zip


此次发布的beta版固件修复以下问题:
1.优化了音频进程的响应速度,解决了因此导致的掐头问题。

2.改进了SD卡响应机制,极大的减小了因热拔插SD卡导致死机的概率。

3.调整了更新逻辑,更新中禁止用户操作,避免因此导致死机的问题。增加了对SD卡总容量的判断,总容量不变的情况下跳过更新,缩短了开机时间。

4.修复了超长播放列表(特别是全部歌曲)导致内存不足而死机的问题。

5.修复了在顺序播放模式下,播放最后一首歌结束时极小几率导致死机的问题。

6.修复了在无缝播放模式下,播放中修改随机/循环模式可能导致死机的问题。

7.修复了特殊情况下出现声道反转的问题。

8.调整了部分列表的显示内容和显示排序。

9.增加了对wv文件格式的支持。

10.增加了对韩语的支持,同时对各种语言新增加的字符串完成了本地化。

11.增加了对底座的支持。

12.增加了数字芯片滤波功能。
(注:HM-802无此功能)

注:此版本为测试版本,建议有一定经验的高级用户升级,正式版本将于一周后发布。

HM-901及HM-802固件升级操作:

1. 拷贝下载的update.zip文件(文件名不能更改,不用解压出来)至SD卡(请使用FAT32格式的SD卡)根目录(卡中存在的其他文件不影响升级操作);

2. 长按home键,向上拨动power键并保持,开机,屏幕亮后松开power键,等hifiman开机logo消失后松开home键,机器将进入recovery功能;

3. 出现首张画面后等待,系统将自动开始升级操作;

4. 升级进度结束后,将机器关机后再次开机升级过程全部完成。

Mine shows red light at the charger, had it for an hour but the unit does not seem charged.

You must have one of those new chargers then. The new one shows red while charging, and turns green when it's done.
 
It takes quite a long time to fully charge your battery, like 5-6 hours minimal.

You need at least more than 5 hours of charging and then it will show green. Do not discount when just turn green. Let it charge some more. You can check that when it just turned green, u go and off the power supply without unplugging the charging terminal of the player and charger you will see red again. However once you let it charge maybe 15 min more after the green light just turn on ad you do the same as above you will see after switching off the main supply the light indicator will still be in green that shows that your batt now is fully charged.

Anyone have the HM-901 + IEM Card paired staright from the headphone output to the Shure SE846? I am looking at going this route, as I had issues with both the Fiio X3 (UI problems, won't detect tags from ALAC files, and random freezing) and the iBasso DX50 (random volume spikes and lock-ups). I just wanted to see if anyone else is using this combo. I don't want to use an external amp.
 
Thanks,

Just updated from the Dropbox that shared pekingduck.
In general a noticeable improvement.
The fade-in seems to have been addressed but I still hear a little crack or pop just before the track starts, it should be plain clean but fairly it's better this than the fade-in thing, hope Fang will work in a workaround to prevent residual noises.
Cue seems works well.
When updating database will displays the files. Also plays the audio from a video in mp4 that I have in the SD card.
Tried briefly the "digital pass filter", it seems to me sound worse but I don't know exactly what it does. Anybody could explain how this feature works and in which situations could be helpful?

Since this digital filter is only available to HM901 and not HM802 (where both runs on the same hardware besides the DAC section), I'll venture a guess and say the digital filter is referring to the filters built into ES9018, which allows user to set between either a slow or a sharp roll-off.
