Investigation of this issue revealed that when a single DDR chip select is used, the hang does not happen. It only happens when the two chip selects are active. MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence": "The controller must keep the memory lines quiet (except for CK) for the ZQ calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256 for other ZQCL and 64 for ZQCS)." According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL: "Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines. Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)" So make sure to activate one chip select at time (CS0 first and then CS1 later), so that the required JEDEC delay is respected for each chip select. With this change applied the board has gone through three days of reboot stress test without any hang.

| * | arm: mxs: Enable booting of mx28 without batteryGraeme Russ2015-02-10-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section 4.1.2 of Freescale Application Note AN4199 describes the configuration required to operate the mx28 from a 5V source without a battery. This patch changes the behaviour of the dropout control of the DC-DC converter (refer to section 11.12.9 of the mx28 Application Processor Reference Manual - Document Number: MCIMX28RM, Rev 2, 08/2013) to the following: - Always use 4P2 Linear Regulator if CONFIG_SYS_MXS_VDD5V_ONLY is defined - Switch between 4P2 Linear Regulator and Battery, using whichever has the highest voltage if CONFIG_SYS_MXS_VDD5V_ONLY isnot set (this is the same as the pre-patch behaviour) Signed-off-by: Graeme Russ <gruss@tss-engineering.com> Signed-off-by: Damien Gotfroi <dgotfroi@greenwatch.be>
| * | arm: mxs: Add debug outputs and comments to mxs SPL source filesGraeme Russ2015-02-10-5/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is difficult to track down fail to boot issues in the mxs SPL. Implement the following to make it easier: - Add debug outputs to allow tracing of SPL progress in order to track where failure to boot occurs. DEUBUG and CONFIG_SPL_SERIAL_SUPPORT must be defined to enable debug output in SPL - Add TODO comments where it is not clear if the code is doing what it is meant to be doing, even tough the board boots properly (these comments refer to existing code, not to any code added by this patch) Signed-off-by: Graeme Russ <gruss@tss-engineering.com>
