The RE6500 was working fine on an old 19.07 snapshot: OpenWrt 19.07-SNAPSHOT r10578-b3d70f628b
I sysupgraded to latest snapshot and it does not come up. Judging from the LEDs, it seems to bootloop.
Booting the latest snapshot initramfs through TFTP works. I sysupgraded again from the initramfs, and it still bootloops.
Possibly related to FS#3539. I will try to get a serial output to see what happens.
The text was updated successfully, but these errors were encountered:
Ok, on the serial port, it goes up to:
U-Boot 1.1.3 (Jun 2 2015 - 15:52:13)
Board: Ralink APSoC DRAM: 64 MB
relocate_code Pointer at: 83f20000
It spends several seconds here, and then reboots.
According to the wiki, there should be kernel boot log just after this point.
Sorry, something went wrong.
It works with a self-built image on r15386-c22b689cf8
Probably an issue with kernel size, my build:
u-boot legacy uImage, MIPS OpenWrt Linux-5.4.85, Linux/MIPS, OS Kernel Image (lzma), 2407280 bytes, Fri Jan 1 12:22:58 2021, Load Address: 0x80001000, Entry Point: 0x80001000, Header CRC: 0xB38001C5, Data CRC: 0x402476AB
vs snapshot build:
u-boot legacy uImage, MIPS OpenWrt Linux-5.4.85, Linux/MIPS, OS Kernel Image (lzma), 2512013 bytes, Thu Dec 31 22:09:09 2020, Load Address: 0x80001000, Entry Point: 0x80001000, Header CRC: 0x43D6213D, Data CRC: 0x8CD79BE0
Looks like 8 MiB flash, how big is the kernel 'partition'? Or does mt7621 use a dynamic splitter?
Yes it's a 8 MB flash device.
Good question. It looks dynamic to me:
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"
0x000000040000-0x000000050000 : "factory"
0x000000050000-0x000000800000 : "firmware"
0x000000000000-0x00000024bbb0 : "kernel"
0x00000024bbb0-0x0000007b0000 : "rootfs"
0x0000004e0000-0x0000007b0000 : "rootfs_data"
0x24bbb0 = 2407344 (my kernel is 2407280)
