Bricked TL-wr841n about u-boot_mod HOT 7 CLOSED

Hello @N1ght5tar,

If RAM version works without any problems, that means there is some problem in low level initialization. Could you tell me exact revision of the SoC (AR9341-XXXX), please? What memory chip do you have in that WR841v8?

Regards,

Sorry for delay.
I can't exactly tell what the board is, the only info "visible" to me is:
TL-WR841N(RU) Ver:8.4, board rev:1.2
Memory chip: ESMT M13S2561616A

Another thing I may got wrong - I used LZMA compressor from xz-5.0.2 instead of yours (lzma-4.32.7), because I am running pure x86_64. Could this be reason that raw RAM image worked fine but compressed flash is not booting, i.e. no output at all?

Or just read in uboot console "Chip Revision ID" value (common for all ath79):

md 0x18060090 0x1

Deoptim,

If that helps, this is the output from that command:

18060090: 00010123 ...#

@N1ght5tar
Try image from the link below and let me know if it works for you. Different LZMA tool version on your host machine was probably the reason.

@Deoptim
Yes, bits [0:3] should indicate minor revision ID (higher bits are for major ID), here (in @N1ght5tar WR841Nv) we have minor revision ID = 3. I have revision 1 on my desk (the one which I'm using for tests).

Thanks pepe2k, it working!
I guess it's my mischoice of LZMA tool before build.
I will try my image next time I will have another this device.
Close if needed.
