Dear all,
I am trying to get an i.MX28 EVK board running with a 3.1 kernel compiled with buildroot.
To start the linux kernel, I am using the Freescale ROM bootloader as provided by the buildroot mxs-bootlets package.
For the kernel, I am using the standard mxs_defconfig config file available in the 3.1 kernel.
When trying the boot the bootstream from USB via the sbloader tool, the kernel seems to hang at kernel booting:
PowerPrep start initialize power...
Battery Voltage = 2.21V
No battery or bad battery detected!!!.Disabling battery voltage measurements./r/nLLLCMar 11 201513:21:31

ddr2 0x40000000
finish simple test
LLLLLLLFLCLLJUncompressing Linux... done, booting the kernel.
I have seen on several posts on this forum that such issue could be related to serial interface name. I specified in the kernel boot arguments the use of ttyAMA0 but this does not solve the issue
Would anyone have get a 3.1 kernel with the mxs_defconfig config file running on the iMX28 EVK?
Would anyone already have faced such boot problem?
Many thanks in advance for any answer.
Best regards
Adrien
Hello Jimmy,
Thanks a lot for your answer.
I tried it but I am still facing the same issue. I suppose that the parameters I am using on the host side are OK (baud: 115200, data bits: 8, stop bits:1, parity: None, Flow control: None).
Is there any way to know if the problem comes from the tty interface or if the kernel is hanging?
Thanks in advance for any help or advice.
Best regards
