AIR-CAP3502i: need to run again RAM calibration fix
Hello everyone, here's full story ...
I just purchased a lot of three 2nd hand AIR-CAP3502i-E-K9, that were previously set as lightweight. Since I needed autonomous APs, I loaded a 12.4 IOS first, then upgraded to 15.2(4)JA1.
On first device, turning LWAPP to Autonomous set a 'boot system flash' variable of corresponding image. Device booted fine, had 12.4(23c)JA bootloader, everything was fine.
I erased flash, loaded 15.2(4)JA1 image, all went fine.
Then, I reloaded device, but I forgot to change 'boot system flash' variable. My big mistake ... Hopefully, I did not forget to remove boot variable for the two other devices, and everything happened on two others as it should (upgrade process went smoothly).
*NEW* DDR Calibration values detected in EEPROM at 0x1E0
Very strange how production team coded this update, by setting flag at the very beginning of update instead after being updated, thus leading to this issue ...
I noticed in directory file 'ap3g1-boot-m_upg' - perhaps I should try to trigger it manually like times we had to upgrade bootloader of 1200 devices a long ago (command like 'copy tftp://.../c1200-boot-m... bs')
Obvously, I don't want to RMA this device, since it has no contact - and I don't plan to pay for a smartnet for an AP, especially for home use, BTW.
If someone has an idea/a set of commands, a hammer, even a soldering iron to sort that out, this is very welcome!
