Topic: 32MB flash in TL-MR11U/AR9331-based HW

The content of this topic has been archived between 7 Apr 2018 and 22 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Congratulations!!
Excellent job!!

I see that new SPI chips have Extended registers/ bank registers
like N25Q512A or spansion chips
potentially we can use some glue code to do hardware mapped memory access inside each 16M blocks with 24bit address mode

where do you quilt patch in??

Guys,
I manage to get 32MB SPI chip recognize by openwrt.
However wireless init fail.
I have copied ART partition and locate it at the end of SPI address 0x000001ff0000-0x000002000000
Please help .... Anything I'm missing here?

gerritb,
can you explain a bit details why change "(u8 *) KSEG1ADDR(0x101f1000);" instead of "(u8 *) KSEG1ADDR(0x1fff1000);" will solve this issue?
which physical address you locate ART partition in this case?

Since no reply yet, I try to analyze this by put printk comment to check physical address
printk(KERN_DEBUG "KSEG1ADDR(0x101f1000) = %0x8x \n",(u32)ee);

Strangely, no message dump out during boot up
check kernel config and already support printk
i guess, i'm stuck now waiting for help

- check your compilation settings / your Kernel commandline
KERN_DEBUG is probably only printed when there is a "debug" string in cmdline.
Either add sth. to that Kernel commandline (afaik somewhere in target/linux/<arch>/image/Makefile - look for the other components of the kernel cmdline (tty , boardname) // don't know if you can change the cmdline with some setting

alternative:
instead of DEBUG use INFO, WARN or ERROR

- regarding KSEG1 / address debugging

This area is most often used for I/O addresses and boot ROM.

notice some boot messages from multiple different MIPS based boards

FLASH: 0xbf000000 - 0xbf7f0000, 128 blocks of 0x00010000 bytes each.
eth0: Atheros AG71xx at 0xb9000000, irq 4
..
ralink flash device: 0x1000000 at 0xbf000000
...
serial8250.0: ttyS0 at MMIO 0xb8020000 (irq = 19) is a 16550A

A physical device like ethernet chip a flash chip is mapped to an address.
So reading from that address reads the Flash content.
You have a flash chip with addresses from 0... mapped to
some space in in 0xA000,0000 (KSEG1 start) -0xBFFF,FFFF (KSEG1 end)

Example: Carambola2 (mach-carambola2.c in build_dir/target.../linux-arch../linux-3.14.x/arch/mips/ath79/)
The KSEG1ADDR is a macro - afaik the address is
A000,0000+offset when KSEG1ADDR(offset) is used
using 1fff,000 means BFFF,0000
Now keep in mind - one msg from earlier - at mips the Flash is (always?/often) mapped at 0xbf00,0000 ....
so you have an remaining offset of 0xff,0000

Compare this to the art partition start on the wiki page: http://wiki.openwrt.org/toh/8devices/carambola2

At least that how I understand this works. Feel free to correct smile
you can search with grep or for commit correcting WMAC/MAC detection or the different flavors of how the MAC/PCI init with KSEG1ADDR is done on the MIPS platform.

you can search with grep or for commit correcting WMAC/MAC detection or the different flavors of how the MAC/PCI init with KSEG1ADDR is done on the MIPS platform.

zloop,
thank's for explanation.
I understand for carambola example since flash map at 0xbf00,0000
so for getting art partition then needs KSEG1ADDR(0x1fff0000)
However for this TL-MR11U / TL-MR3040 device, my understanding flash map at 0x9f00,0000
http://wiki.openwrt.org/toh/tp-link/tl-mr3040
You can see in link above when update openwrt will erase at 0x9f02,0000
but why for getting art partition needs KSEG1ADDR(0x1fff1000) ?

In this thread topic, flash upgraded to 32MB then mips comments

mips wrote:

The "(u8 *) KSEG1ADDR(0x1fff1000);" will auto map to the end 64k of the flash,no matter your flash is 4M/8M/16M.but now it's not work.
When access flash more than 16M,you can't use this SoC aready mapped address.

then gerritb said to have work-around this, to read art partition he change art location and change KSEG1ADDR like comment below

gerritb wrote:

Alternatively, I merged the ART partition into the second sector of the flash so I could change the KSEG address to 0x101f1000.

My understanding cannot follow this
If flash start map at 0x9f00,0000 then won't cover KSEG1 + 0x1fff,ffff
So if KSEG1ADDR(0x101f1000) where is art physical address located?

for ramips there is
- https://dev.openwrt.org/browser/trunk/t … dule.patch

The difference between 0x9f.. & 0x8f.. is according to documents if its cached or not cached.
( http://www.eecs.harvard.edu/~mdw/course … b-cpu.html )

The Flash can be mapped multiple times into RAM.

According to the "AR9331 data sheet"

"Upon reset, the CPU puts out an address of 0xBFC00000 which is mapped to the flash address space or internal ROM code, using an external pull up/down register to choose if the AR9331 will boot from
the Flash or internal ROM.

regarding the addresses:
Check an u-boot partition dump - there is probably some string/u-boot-env mini settings partition
and offset 0x1,fc00 contains the MAC (use "strings" to check for readable string inside the dump)

Thank you again for details explanation.
I think I understand now this original memory map, but correct me if I'm wrong.
By default re_map disable so flash address is 0xBFC00000 ~ 0xBFFFFFFF
That will give total flash space only 4MB .

In this topic flash chip modified to 32MB flash chip.
Originally to access ART partition (mtd4) which located in the last 64KB.
That's why the code to read this partition will be "(u8 *) KSEG1ADDR(0x1fff1000);"  (KSEG1ADDR(0x1fff0000) + 0x1000 offset where radio wireless initialization parameter located).

The thing that I still don't understand when flash modified to 32MB, gerritb said :

gerritb wrote:

Alternatively, I merged the ART partition into the second sector of the flash so I could change the KSEG address to 0x101f1000.

He relocated ART partition to different address and to read this wireless initialization parameter, change the code to "(u8 *) KSEG1ADDR(0x101f1000);".
This translate to KSEG1ADDR(0x101f0000) + 0x1000 offset where radio wireless initialization parameter located.
KSEG1ADDR(0x101f0000) translate to virtual address 0xB01F0000.
This is below where CPU starts to read 0xBFC00000 like mention in datasheet. This really puzzle me, where is this physical flash address located?

I check u-boot dump binary and cannot find "u-boot-env" string.
Also u-boot-env.bin doesn't mention partition where MAC address located.
MAC offset location 0x1,FC00 translate to 127KB
Based on TL-MR3040 wiki, mtd size > 127K only u-boot, kernel or rootfs,
so most likely MAC address in u-boot partition.
Does it mean KSEG1ADDR(0x101f0000) = u-boot partition?

@dony71 AR9331 can map only 16 MB for FLASH in address space and because of that you have to reallocate ART partition, to be able to read data from it using direct access (mapped memory).

My question which address location of art did gerritb moved to?

U-Boot set bit REMAP_DISABLE to 1 in low level initialization stage, so whole 16 MB is accessible later.
Take a look here too: https://forum.openwrt.org/viewtopic.php … 23#p193023

As far as I understand, gerritb merged ART with second sector (every sector is 64 KB) in FLASH.
http://www.tech-blog.pl/wordpress/wp-content/uploads/2013/03/tl-mr3020_flash_layout.gif

MAC address in MR3020 (and in most of TP-Link devices) is stored in second sector too, at offset 0x1fc00 (from begin of FLASH) or at offset 0xfc00 (from begin of second sector), rest of the second sector is empty and not used. So, MAC address offset is:

u8 *mac = (u8 *) KSEG1ADDR(0x1f01fc00);

ART partition is always in last 64 KB sector (the following code maps always to last sector, no matter what FLASH size you have - you can use FLASH chip with 4, 8 or 16 MB, with ART partition in last sector and you won't need to change the code). Usable data starts inside ART partition at offset 0x1000, so we use the following offset:

u8 *ee = (u8 *) KSEG1ADDR(0x1fff1000);

IMHO, if you merge ART data with second sector, address should look like:

u8 *ee = (u8 *) KSEG1ADDR(0x1f011000);

I don't know why gerritb wrote about 0x101f1000 address.

Take a look also at DIR-505 initialization, that device has ART partition in second sector, in FLASH:

[...]
#define DIR_505A1_ART_ADDRESS          0x1f010000
#define DIR_505A1_CALDATA_OFFSET       0x1000
[...]
u8 *art = (u8 *) KSEG1ADDR(DIR_505A1_ART_ADDRESS);
[...]
ath79_register_wmac(art + DIR_505A1_CALDATA_OFFSET, lan_mac);

So, the final address is also KSEG1ADDR(0x1f011000).

thanks pepe2k for that great writeup

pepe2k,
you're the man !!
very well explanation clearing my confusion.
thank's very much for spending time to explain this in this great open forum community .

btw, i know you make U-Boot mod for routers with AR9331/AR9344 at
https://forum.openwrt.org/viewtopic.php?id=43237
my understanding this mod doesn't support 32MB flash.
when i try to flash firmware in webfail-safe mode, my u-boot got corrupted.
can you give me some hints where in code to modify to support 32MB flash?

How exactly your U-Boot got corrupted? FLASH related functions are here: https://github.com/pepe2k/u-boot_mod/bl … 40_flash.c

In fact region corrupted is more than uboot sector.
Flash 0 ~ 0x16,ffd0 corrupted.
I notice base address is 16M in ar7240_spi.c
I think there will be extensive code modification to support 32M,
which might be beyond my ability to tweak.

I implement KSEG1ADDR(0x1f011000) like pepe2k suggestion and no problem anymore with wireless initialization. however i have another problem now.
when i do reboot either from openwrt gui or from ssh console, kernel will hang.
below is the  kernel dump. anybody knows why?

earlier i'm using trunk to patch this and it seems kernel is being changed in  latest trunk chaos calmer made impossible this patch to work. reboot command will result always hang.
i verify the patch on barrier breaker and it works.
does anybody know how to apply this patch on current trunk?

This is exactly problem I reported earlier
As I mention high likely kernel issue
I already issue ticket for this
