<body class='hmmessage'><div dir='ltr'><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;">I am working on bringing up two Linux systems, both based on Freescale PowerPC devices, one is a MPC8349, the other a P1020. I was able to build, install and boot the kernel on both cards. The kernel is 2.6.32 and the toolchains are coming from the LTIBs packages from Freescale. </p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;">Both cards have a 32 MByte NOR flash memory (AMD) boot flash. I have Uboot, kernel, RAM disk image and DTB in the boot flash and I want to use the spare space (about 20 MBytes) as flash file system. </p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;">I have the following problem : the P1020 board boots fine using the RAM disk with the flash in the device tree , shows the flash device partitions (JFFS2) and DOESN"T try to mount a flash partition as root. The MPC8349 boots fine from the RAM disk but, after identifying the flash partitions, the kernel panics because is looking for a flash partition to mount as root partition and none of them is usable (not formatted). If I remove the flash from the device tree, the card boots fine using the RAM disk.</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;"><br></p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;">I am not too familiar with Linux boot scripts and I didn't figure out where I can disable this tentative of mounting the MTD partition. I want the boards to boot and mount the RAM disk, as the P1020 board does. The flash partition will be initialized and mounted at a later time, but not as root partition.</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;"><br></p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;">TIA</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;">Dorin</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; word-wrap: break-word; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 18px;"><br></p> </div></body>
